Around the World in 60 Years – The Saga of Offshore PlatformsDr. Robert Bea

This talk traces the 60-year history of one of engineering’s most successful adventures–development of offshore plat-forms used for production of oil and gas reserves. This his-tory starts in the Gulf of Mexico in 1948 in less than 6 meters of water. Today, more than 10,000 major offshore platforms have been placed in the world’s oceans out to water depths of 4,000 meters.

Manufactured Products & Evaluation ReportsBy Reinhard Ludke, S.E.SEAONC President

This article is based on a recent SEAOSC News articles by SEAOSC President Williston (Bill) L. Warren IV, S.E. SEAOSC President.

Many structural engineering projects include manufactur-er’s components that have gone through a certification pro-cess. You rely on the ICBO and the Evaluation Reports (ER) from ICBO Evaluation Service (ES) and are comfortable with the acceptance of these products when they are accompa-nied by an ER. Now with the 2006 IBC the ICC ES/ERs are not approvals; they are information for the building official who determines whether the product complies with the IBC. Now that the responsibility is solely on the building official, does this mean that the building official (BO) knows this? Is the BO capable of performing this task? Does the Engineer of Record (EOR) know this, and is the EOR capable of performing this task?

Engineers specifying pre-manufactured products must un-derstand the testing and acceptance of each of the products specified. For instance, there are several alternatives to tim-ber sheathed shearwalls; they include manufactured tim-ber shearwall components and also include steel alternate components. Prior to the ES preparation of the ER for any item, testing is to be performed on that item as described in the ES Acceptance Criteria (AC). Each AC describes the testing used to determine the seismic design coefficients for that component and the allowable load and drifts. Would it

Continued from Page 1A Message from the President

surprise you to find out that the same AC is not used for all of these products? What occurs when a new product is pro-posed when the AC do not exist or the manufacturer says they do not exist? The manufacturer prepares the AC for the ES. Now this may not be the final draft of the AC, but it is the direction the AC will take. This leads to elements that are intended to perform the same that are not tested in simi-lar manner or even to the same criteria.

Just as the 1997 UBC described “Undefined structural sys-tems” for Earthquake Design, the 2006 IBC allows, in Sec-tion 12.2 of ASCE 7, the use of undefined systems in a similar fashion as seismic force-resisting systems with equivalent dynamic characteristics. This specifically states “Seismic force-resisting systems that are not contained in Table 12.2-1 are permitted if analytical and test data are submitted that establish the dynamic characteristics and demonstrate the lateral force resistance and energy dissipation capacity to be equivalent to the structural systems listed in Table 12.2-1 for equivalent response modification coefficient, system overstrength coefficient and deflection amplification factor values.”

Last year a group of Structural Engineers and members of the SEAOC Seismology Committee formed an Equivalency Committee for ICC ES to create an “equivalency” procedure for timber sheathed shearwalls. The results of this work can be found in ICC ES AC 130 and 322, which describe the 4 points of comparison between proposed alternates and tim-ber sheathed shearwalls to gain the coveted R=6.5. Many of the manufacturers want this R=6.5 for their products, so the recommendation is that each EOR completely understand the testing, the result of that testing and how that testing translates to the information in the ER. The EOR should also understand how the testing compares with timber sheathed shearwalls and how the capacities and drift descriptions of the manufacturers’ products compare with the underlying assumptions of timber sheathed shearwalls.

ICC ES sought input into the criteria development. If you go to the ICC ES website http://www.icc-es.org/Criteria_Develop-ment/balloted.shtml and then click on the “MISC1” link you can read the letter describing its request. This is a good site to which to refer, and this is the site where the Acceptance Criteria gets developed and discussed prior to all of us hav-ing to live with it, so if we do not comment and participate we may end up with things we do not like.

ICC ES and its ERs are not the ICBO ES/ERs. Before speci-fying a pre-manufactured item with an evaluation report, ask questions. For those manufacturers that state that their product complies with the 2006 IBC, you could check the ICC ES website for its position on product use with the 2006 IBC. You may look at the ER that is being used to state com-pliance with the 2006 IBC and understand the AC used for testing the product. Looking at the test results may help you confirm that you are using products that meet the Code and your intended structural performance objectives.

SEAONC Special Projects Initiative Awards

Greg Deierlein

The SEAONC Board is pleased to announce two $10,000awards for special project initiatives to improve and pro-mote structural engineering practice. David Bonowitz isthe recipient of an award to develop resilience criteria forseismic evaluation of existing buildings. By articulatingways to assess the time to recover basic operations afteran earthquake, the resilience criteria developed throughthis project will enable engineers to address client’s con-cerns regarding facility downtime and how it may be miti-gated.

The second award goes to Kevin Moore of Certus Consult-ing and Andy Fennell of Scientific Construction Labora-tories to test and evaluate anchor bolt capacities for wood framed construction. The project will investigate what to many engineers appear to be overly conservative capaci-ties for anchor bolts used for wood frame construction in the 2006 IBC.

Finally, the SEAONC Board would like to acknowledge and thank everyone who submitted excellent completing proposals for the 2008 Special Projects Initiative. Subjectto available funds, the Board looks forward to continuingthe initiative with another competition next year.

Thoughts and comments-

The reason I asked Bill Warren if I could disseminate his article on Evaluation Reports is to provide SEAONC mem-bers the background on current product Evaluation Reports process and procedures. In my practice, I have accepted the ICBO ER document and used the capacities and perfor-mance indicated with reductions that might be specified by OSHPD or DSA for hospital or school projects. The SEAOC Recommended Guidelines for the Practice of Structural En-gineering in California says in Chapter 1, Section 7.2 that “The engineer should use sound engineering judgment in reviewing such products, but is not required to verify the technical data.” I believe this has been the standard practice in our profession. My opinion is that knowing the testing and Evaluation Report procedures gives the engineer more information to make more informed decisions. I don’t be-lieve that we have to research and inspect every product evaluation, but now you know the background. If you have comments or more knowledge about this, please provide your comments to me or to the SEAONC office, and we will publish your information in a future NEWS article.

ATC-20 Training Seminar Wrap-up

Brian DiBarnabaDES Committee Chair

The DES committee sponsored and organized the ATC-20 Training Seminar at Santa Clara University on Saturday, November 1st. Aside from a little wet weather, the Semi-nar was a great success. The purpose of the ATC-20 pro-gram is to provide guidelines and procedures for the post earthquake evaluation of buildings. ATC-20 was developed in 1987, and ever since, the SEAONC DES Committee has sponsored and organized training seminars on the subject on regular basis. This year attendees received classroom training on ATC-20 procedures, information on hazardous materials, what to expect on a deployment, as well as hands-on building evaluation experience through case studies. SEAONC and the DES Committee would like to express a special thank you to all of our presenters: Meaghan Hal-ligan, Michael Fretz, John Osteraas, Ray Lui, Joe Zsutty, Bob “Bubba” Haag, Zan Turner, David McCormick, David Bonowitz, Jeff Falero, Cynthia Perry, and Eduardo Fierro. I would also like to thank DES Committee members Bryce Dickinson, Tanjeet Juneja, Don David, Marlou Rodriguez, and Sean Timon for their hard work and preparation. Al-though I my opinion may be a little biased, these present-ers along with the SEAONC DES Committee help make our ATC-20 Training Seminar one of the best training seminars on this subject in the state.

Dec. 2nd Monthly MeetingContinued from Page 1

This history has been based on a wide diversity of advanced engineering technologies including earthquake engineer-ing. One of the hallmarks of this development has been construction engineering and equipment which have al-lowed the largest structures ever constructed by people to be moved, installed, and maintained in some of the most challenging parts of the world’s environments – its unfro-zen and frozen oceans. The technologies developed in the field of earthquake engineering have played important roles in helping develop understanding of the oceans dynamic loadings and conditions ranging from 30 meter high ocean waves to impacts from one million ton icebergs. Similarly, many of the lessons learned in earthquake engineering about performance based design of steel and concrete struc-ture – foundation systems have found their way into the en-gineering technology of offshore platforms.

This talk concludes with a discussion of some of the ‘hot topics’ that are being addressed currently by this industry including:

•platform ‘geriatrics’ – or requalification of existing platforms for extended service; •engineering ‘minimum’ – low initial cost – structures; •design of robust – damage and defect tolerant - structural systems; and •learning from failures – the importance of the human elements.

Dr. Bea is a professor of Civil and Environmental Engineer-ing at the University of California Berkeley. He has worked with the international offshore oil and gas industry for the past 49 years in design, construction, operation, mainte-nance, and decommissioning of offshore platforms in every major ocean except the Antarctic.

SEAONC MEMBERS VOLUNTEER IN OAKLAND BUILDING SURVEY

Colin Blaney, David Bonowitz and Marko Schotanus

As announced in previous newsletters, the Association of Bay Area Governments (ABAG) organized a survey of multifamily residential buildings with potential soft-story hazards for the City of Oakland in September and Octo-ber. The goal of the survey was to collect data to develop a soft-story ordinance and possible retrofit program.

SEAONC helped with volunteer recruitment and provided input on general survey organization as well as the type of data to collect. SEAONC also helped sponsor the break-fast and lunch for the volunteers.

Many SEAONC members volunteered and participated in the survey. They were joined by others from the Earth-quake Engineering Research Institute – Northern Califor-nia Chapter, the American Institute of Architects – East Bay, the American Society of Home Inspectors – Bay Area, and engineering students from UC Berkeley, San Francis-co State, Stanford, and San Jose State.

As part of the survey, all volunteers were trained to in-crease the quality of the data collected. After the training session the volunteers were divided up into teams of two, and sent out to pre-selected buildings throughout the City of Oakland. Building locations were selected from the assessor’s database, based on number of stories, number of units and year built.

Around 120 volunteers looked at over 3500 parcels throughout Oakland on three Saturdays. Remaining buildings will be surveyed by volunteers of the City of Oakland’s Public Works Department and ABAG, complet-ing data collection by the end of November 2008.

Based on the data collected the first Saturday, about 30% of the buildings reviewed appeared to have classical soft-story characteristics including overall wood frame con-struction with open parking over a large portion of the ground floor.

Based upon the past performance of these types of struc-tures, it is well known that a moderate to large earthquake could damage these multi-family residential buildings thus impacting and possibly displacing residents perma-nently. With the full support of City of Oakland council members Jean Quan and Nancy Nadel, it is our hope that this data will help shape future policies or programs that ultimately lead to a more resilient community. Earthquake preparedness benefits both residents and businesses, and through this effort SEOANC and its members have made a tangible difference in the City of Oakland’s seismic fu-ture.

The Existing Buildings Committee will track results and further developments. For more information or to join the committee mailing list, please contact Colin Blaney at [email protected]. More information and updates are also available on the web at http://quake.abag.ca.gov/Oakland-Housing.html.
