11. Strengthening Bridges by Developing Composite Action in Existing Non-Composite Bridge Girders Michael Englehardt, Ph.D, P.E., UT

A number of older bridges are constructed with floor systems consisting of a non-composite concrete slab over steel girders. A potentially economical means of strengthening these floor systems is to connect the existing concrete slab and steel girders to permit the development of composite action. This presentation will discuss the results of a research study sponsored by the Texas Department of Transportation, examining a variety of methods for post-installing shear connectors in bridge girders. This presentation will summarize the research program and the resulting design recommendations. Application of this research for strengthening of a bridge located near Hondo, Texas will also be presented.

1: Solving the Riddle of Concrete Shear Strength Robert Frosch, Ph.D, P.E., Purdue University, West Lafayette, Indiana

9:00 am - 9:50 am 1.0 PDH

2: Ultimate Strength and Inelastic Behavior of Braced Frame Gusset Plate Connections Charles Roeder, Ph.D, P.E., University of Washington,

9:50 am - 10:40 am 1.0 PDH

10:40 am - 11:00 am

3: Design of High-Rise Concrete Buildings John Tessem, P.E., S.E., Principal, DCI Engineers, Bellevue, Washington

11:00 am - 11:50 am 1.0 PDH

John is a principal with DCI Engineers and has 25 years of experience working as a structural engineer designing many building types. He has focused on the design of concrete high-rise residential, hospitality, and office towers. He is an active member of ACI Committee 374 Performance-based Design of Concrete Buildings; ASCE Tall Buildings committee; CTBUH, PTI, and SEAW. He has made numerous presentations on concrete tower design at various domestic and international conferences including ACI International, ASCE Structures Congress, and Structural Engineers Association of Washington (SEAW).

With rising costs of building construction structural engineers are challenged to produce cost effective designs. Concrete framing systems, high production formwork, utilization of building materials, concrete mix designs are critical to cost effective structures. Structural layout and innovative design methods including performance-based design methodologies are utilized to produce efficient structural frame designs. A case study of a major Seattle project will illustrate the components of design and construction of concrete tower projects.

Charles Roeder is a Professor of Civil Engineering at the University of Washington (UW). He has served on the faculty for 32 years, and has performed a range of research related to the seismic performance of steel and composite structures. He is a member of a number of professional organizations including ASCE, AISC & SEAW. He is presently a member of the Board of Directors and Corporate Secretary of the NEES Consortium, and a member of the Executive Committee for the ASCE/Structural Engineering Institute. He received the 2002 AISC Special Achievement Award, and the 2002 Puget Sound Engineers Council Academic Engineer of the Year.

Braced frames are widely used for a wide range of structural applications. They develop substantial strength and stiffness, and with proper care in design achieve the ductility and inelastic deformation capacity needed for seismic performance. Gusset plate connections are an integral part of braced frames, since they join the braces to the beams and columns of the frames. These connections must develop the resistance of the brace and the frame and accommodate the inelastic deformations required during seismic loading. This presentation focuses on design methods and inelastic performance of gusset plate connections. The research work was motivated by seismic design requirements, but the implication of the research results has much broader implications for the design of lateral load resisting systems.

The shear strength of structural concrete has been investigated for well over 100 years. While significant progress has been made in the understanding of shear behavior, the advent of alternative reinforcing materials has provided clues that can be used to solve this ongoing riddle. This presentation will explore a new theory regarding the resistance of concrete to shear. Using this theory, a simplified design procedure is developed that can be used for the shear design of structural concrete members reinforced with either steel or fiber reinforced polymer (FRP) bars. Furthermore, the applicability of the design approach to prestressed as well as partially prestressed members will be explored.

Awards & Honors

2009 SEAoT Hall of Honor Award Recipient — Elmer W. Ellisor Jr., P.E.

Elmer W. Ellisor Jr. was born on June 21, 1923 in Cleveland, Texas. He earned both his BS and MS degrees in Civil Engineering from Southern Methodist University in Dallas. He arrived in Houston in 1955 and worked for the firm of Wyatt C. Hedrick as a structural engineer eventually becoming chief engineer in this office. In 1961, he and co-worker, Louis Gaddy, left the Hedrick firm and started their own consulting firm known as Ellisor and Gaddy. In the mid 1960’s he founded his own firm, Ellisor Engineers. Later, in 1967, he joined forces with John L. Tanner, III to form Ellisor + Tanner in Dallas. People who worked with Elmer say that he was a very knowledgeable and thorough engineer. However,

his main legacy came after he established his own firm, with his ability to market engineering services and to assemble the organization to produce this work. He successfully marketed structural engineering services to most of the major developers in Houston and Texas. He was always eager to incorporate new and innovative structural systems and construction methods in his projects. He worked closely with contractors to evaluate the feasibility and cost effectiveness of new ideas. He surrounded himself with other engineers that were experts in different areas of structural engineering, including pre-cast and pre-stressed concrete, high rise buildings and computer applications to make this possible. The Hall of Honor is in its 5th year and with Elmer has eight “pioneers” of structural engineering in Texas. Our charge as we go forward is to continue to grow the Hall of Honor in stature and prestige, by the additions of many more outstanding engineers, engineering educators and contributors to the engineering community.

From Oct. 2006 through Sep. 2009, the US National Science Foundation sponsored a project on performance-based design of masonry and masonry veneer. That project includes shaking-table testing of a full-scale, one-story structure of reinforced and fully grouted concrete masonry, with clay masonry veneer. This presentation will discuss the structural design and findings of this project. The structure, designed in accordance with the 2008 MSJC code and specification, suffered only minor damage under ground motions consistent with the design basis earthquake (DBE), and did not collapse under repeated ground motions in excess of the maximum considered earthquake (MCE), with peak ground accelerations as high as 2.69 g. Response was consistent with design objectives and with pre-test predictions.

Finding a path to sharing the skills and experience you acquire in your work life with the wider community is worth working for and brings its own rewards. Leadership should extend outside of the office but does not have to be separate from your work. Find ways to share your passion and your skills to make a difference in your community.

The new segmental bridge which crosses the Gulf Intracoastal Waterway and connects the Matagorda Peninsula to the Texas mainland having a span of 320 feet possesses a number of striking architectural features. The Lubbock pedestrian bridge located adjacent to Jones stadium and completed in the summer of 2008 began swaying laterally when fully loaded with pedestrians upon the conclusion of a football game. Many characteristics of the bridge and site worked in unison to allow the bridge to sway. Numerous retrofit schemes were modeled and explored with a final solution that began construction in the spring of 2009.

1:00 pm - 4:00 pm Presentations Friday, Oct. 30

6: Lessons Learned about Offshore Production Facilities in Recent Hurricanes Robert Gilbert, Ph.D, University of Texas, Austin, Texas

Four of the strongest hurricanes on record recently passed through the offshore oil and gas facilities in the Gulf of Mexico: Hurricane Ivan in Aug. 2004, Hurricane Katrina in Aug. 2005, Hurricane Rita in Sep. 2005 and Hurricane Ike in 2008. The cumulative impact of these storms was significant, with hundreds of platforms destroyed, billions of dollars in property loss, and hundreds of million barrels of oil production removed from the U.S. oil supply. Remarkably, there were no fatalities or injuries to offshore workers because they were successfully evacuated in advance of each storm. This talk will address what happened and what we have learned from these intense hurricanes, including hurricane forces, wave-induced mudslides, and the performance of temporary drill rigs, permanent production facilities and pipelines

Dean graduated from the University of Texas-Austin with a BSCE in 1982. He immediately began his career as a bridge designer with TxDOT (Texas Department of Transportation). He returned to UT-Austin where he earned a MSE in 1991 with an emphasis in structural engineering. He is currently a senior design engineer with TxDOT. He has designed numerous bridges at TxDOT with an emphasis on prestressed concrete bridges.

Oftentimes in low and moderate seismic zones, the design engineer is faced with the question early in preliminary design about whether wind or seismic loads will govern the design. This presentation will focus on this question and offer some guidance on a rational preliminary design procedure to use for a project. Particular attention will be given to important aspects of establishing the structural system as it relates to the design for both seismic and wind loads.

Dinner Banquet & Evening Social 6:30 pm - 11:00 pm

—- Break with Exhibitors —- 4:50 pm - 6:30 pm

With the world's growing dependence on engineering and technology, increasing numbers of public, industry and community leaders need to be well versed in the complexities and nuances of both. The situation, coupled with the instability of global marketplaces and economies, ever-present infrastructure and environmental concerns, and an exploding world population, demands that honest pragmatic thinkers be in positions of high leadership and authority. As professionals intuitively having such qualities, more engineers than ever before need to step forward and be heard, and get meaningfully involved in helping set public direction and policy. Discussed are why it's good business for structural's to do that -- and why it behooves them to “run things and not just make things run” -- and what steps can be taken to prepare for necessary leadership roles within and beyond engineering.

Please join us for a very special evening including dinner, awards and live music. Say hello to old friends and meet new ones during one of the two evening socials. Please use your drink tickets for a select choice of beer and wine followed up by a fabulous three course dinner. During the banquet, we are pleased to present this years Honorary Members, SEAoT Service, Wilber C. Schoeller and Hall of Honor award winners followed up by our Keynote Speaker Mr. Richard Weingardt. Please stick around after the presentation to socialize and be entertained with live music by the Rick McRae Quartet.

Balancing a demanding professional life and personal time is a challenge for everyone, and sometimes finding time to donate to community outreach seems impossible. Finding a path to sharing the skills and experience you acquire in your work life with the wider community is worth working for and brings its own rewards. Leadership should extend outside of the office but does not have to be separate from your work. Find ways to share your passion and your skills to make a difference in your community.

The new segmental bridge which crosses the Gulf Intracoastal Waterway and connects the Matagorda Peninsula to the Texas mainland having a span of 320 feet possesses a number of striking architectural features. The Lubbock pedestrian bridge located adjacent to Jones stadium and completed in the summer of 2008 began swaying laterally when fully loaded with pedestrians upon the conclusion of a football game. Many characteristics of the bridge and site worked in unison to allow the bridge to sway. Numerous retrofit schemes were modeled and explored with a final solution that began construction in the spring of 2009.


6: Lessons Learned about Offshore Production Facilities in Recent Hurricanes Robert Gilbert, Ph.D, University of Texas, Austin, Texas

Four of the strongest hurricanes on record recently passed through the offshore oil and gas facilities in the Gulf of Mexico: Hurricane Ivan in Aug. 2004, Hurricane Katrina in Aug. 2005, Hurricane Rita in Sep. 2005 and Hurricane Ike in 2008. The cumulative impact of these storms was significant, with hundreds of platforms destroyed, billions of dollars in property loss, and hundreds of million barrels of oil production removed from the U.S. oil supply. Remarkably, there were no fatalities or injuries to offshore workers because they were successfully evacuated in advance of each storm. This talk will address what happened and what we have learned from these intense hurricanes, including hurricane forces, wave-induced mudslides, and the performance of temporary drill rigs, permanent production facilities and pipelines

Dean graduated from the University of Texas-Austin with a BSCE in 1982. He immediately began his career as a bridge designer with TxDOT (Texas Department of Transportation). He returned to UT-Austin where he earned a MSE in 1991 with an emphasis in structural engineering. He is currently a senior design engineer with TxDOT. He has designed numerous bridges at TxDOT with an emphasis on prestressed concrete bridges.

3: Design of High-Rise Concrete Buildings John Tessem, P.E., S.E., Principal, DCI Engineers, Bellevue, Washington

11:00 am - 11:50 am 1.0 PDH

John is a principal with DCI Engineers and has 25 years of experience working as a structural engineer designing many building types. He has focused on the design of concrete high-rise residential, hospitality, and office towers. He is an active member of ACI Committee 374 Performance-based Design of Concrete Buildings; ASCE Tall Buildings committee; CTBUH, PTI, and SEAW. He has made numerous presentations on concrete tower design at various domestic and international conferences including ACI International, ASCE Structures Congress, and Structural Engineers Association of Washington (SEAW).

With rising costs of building construction structural engineers are challenged to produce cost effective designs. Concrete framing systems, high production formwork, utilization of building materials, concrete mix designs are critical to cost effective structures. Structural layout and innovative design methods including performance-based design methodologies are utilized to produce efficient structural frame designs. A case study of a major Seattle project will illustrate the components of design and construction of concrete tower projects.

Charles Roeder is a Professor of Civil Engineering at the University of Washington (UW). He has served on the faculty for 32 years, and has performed a range of research related to the seismic performance of steel and composite structures. He is a member of a number of professional organizations including ASCE, AISC & SEAW. He is presently a member of the Board of Directors and Corporate Secretary of the NEES Consortium, and a member of the Executive Committee for the ASCE/Structural Engineering Institute. He received the 2002 AISC Special Achievement Award, and the 2002 Puget Sound Engineers Council Academic Engineer of the Year.

Braced frames are widely used for a wide range of structural applications. They develop substantial strength and stiffness, and with proper care in design achieve the ductility and inelastic deformation capacity needed for seismic performance. Gusset plate connections are an integral part of braced frames, since they join the braces to the beams and columns of the frames. These connections must develop the resistance of the brace and the frame and accommodate the inelastic deformations required during seismic loading. This presentation focuses on design methods and inelastic performance of gusset plate connections. The research work was motivated by seismic design requirements, but the implication of the research results has much broader implications for the design of lateral load resisting systems.

The shear strength of structural concrete has been investigated for well over 100 years. While significant progress has been made in the understanding of shear behavior, the advent of alternative reinforcing materials has provided clues that can be used to solve this ongoing riddle. This presentation will explore a new theory regarding the resistance of concrete to shear. Using this theory, a simplified design procedure is developed that can be used for the shear design of structural concrete members reinforced with either steel or fiber reinforced polymer (FRP) bars. Furthermore, the applicability of the design approach to prestressed as well as partially prestressed members will be explored.

Awards & Honors

2009 SEAoT Hall of Honor Award Recipient — Elmer W. Ellisor Jr., P.E.

Elmer W. Ellisor Jr. was born on June 21, 1923 in Cleveland, Texas. He earned both his BS and MS degrees in Civil Engineering from Southern Methodist University in Dallas. He arrived in Houston in 1955 and worked for the firm of Wyatt C. Hedrick as a structural engineer eventually becoming chief engineer in this office. In 1961, he and co-worker, Louis Gaddy, left the Hedrick firm and started their own consulting firm known as Ellisor and Gaddy. In the mid 1960’s he founded his own firm, Ellisor Engineers. Later, in 1967, he joined forces with John L. Tanner, III to form Ellisor + Tanner in Dallas. People who worked with Elmer say that he was a very knowledgeable and thorough engineer. However,

his main legacy came after he established his own firm, with his ability to market engineering services and to assemble the organization to produce this work. He successfully marketed structural engineering services to most of the major developers in Houston and Texas. He was always eager to incorporate new and innovative structural systems and construction methods in his projects. He worked closely with contractors to evaluate the feasibility and cost effectiveness of new ideas. He surrounded himself with other engineers that were experts in different areas of structural engineering, including pre-cast and pre-stressed concrete, high rise buildings and computer applications to make this possible. The Hall of Honor is in its 5th year and with Elmer has eight “pioneers” of structural engineering in Texas. Our charge as we go forward is to continue to grow the Hall of Honor in stature and prestige, by the additions of many more outstanding engineers, engineering educators and contributors to the engineering community.

11. Strengthening Bridges by Developing Composite Action in Existing Non-Composite Bridge Girders Michael Englehardt, Ph.D, P.E., UT

A number of older bridges are constructed with floor systems consisting of a non-composite concrete slab over steel girders. A potentially economical means of strengthening these floor systems is to connect the existing concrete slab and steel girders to permit the development of composite action. This presentation will discuss the results of a research study sponsored by the Texas Department of Transportation, examining a variety of methods for post-installing shear connectors in bridge girders. This presentation will summarize the research program and the resulting design recommendations. Application of this research for strengthening of a bridge located near Hondo, Texas will also be presented.
