Team Develops Seismic Upgrade forIstanbulrsquos Ataturk Airport Terminal
(continued on page 2) Friction pendulum devices were installed toseismically isolate the roof of the airport terminal
InsideInsideMCEER researcher Michael Constantinou was part of a team chargedwith the seismic upgrade of Istanbulrsquos Ataturk International AirportThe upgrade of the structure which was under construction at the
time of the August 17 1999 Marmara earthquake and scheduled to open in Janu-ary 2000 was recommended by TEPE-AKFEN-VIE (TAV) the localbuild-operate-transfer consortium of the 190000 square meter terminal and park-ing garage and its advisor on construction management New York-based TurnerInternational The upgrade had to be accomplished prior to the opening of theairport and although the earthquake did not damage the structure TAV wantedto strengthen it beyond the local codersquos requirement for life safety
The design and implementation of the upgrade led by LZA Technology a divi-sion of Thornton-Tomasetti Group New York City took less than four monthsOther team members were Michael Constantinou professor and chair of UBrsquosDepartment of Civil Structural and Environmental Engineering and an MCEERresearcher Andrew S Whittaker Associate Director of PEER University of Cali-fornia at Berkeley and Tuncel Engineering and Fondsiyuon MuhendislikInsaatvetic Ltd both of Istanbul
The modernization scheme consisted of three steps 1) increasing the strength ofthe second- and third-story columns by steel jacketing the columns 2) seismi-cally isolating the roof to reduce seismic demand on third-story columns and3) installing lock-up devices (shock absorbers) at roof expansion joints
Professor Constantinou and his colleagues were involved in the development ofthe upgrade conceptual design evaluating alternate solutions performing non-
linear static and dynamic analysisof the structure and assessingthe displacement demand in theisolation bearings The roof iso-lation scheme involved slicingthe columns horizontally at thetop and installing friction pendu-lum bearings manufactured byEarthquake Protection Systems of

Keith Kesner is a PhD candidate at Cornell University and is currently involved in a project entitled ldquoDevelopment of Engineered Cementitious Composite Materials for SeismicStrengthening and Retrofitrdquo Dr Sarah Billington is his advisor and his expected graduationdate is May 2002 The project is directed towards the development of cementitious compositematerials that exhibit a ldquopseudo strain hardeningrdquo response in tension It is believed that thesematerials have excellent potential for seismic strengthening and rehabilitation applicationsDevelopment of these materials will require laboratory testing to establish fundamental be-havior characteristics and additional testing to verify the performance of components madewith the composite materials Concurrent with the laboratory testingmaterial models will be developed to allow for finite element basedsimulations of the material performance in structural models
According to Keith ldquoThis research represents a transition in the field ofstructural engineering from the use of traditional materials such as re-
inforced concrete and steel to materials with engineered performance characteristics This isone of the many facets of the project that is exciting to merdquo
This project fits well into MCEERrsquos mission to develop new and emerging materials that havepotential for use in seismic rehabilitation of structures These newer materials may possesssignificant advantages over conventional civil engineering materials such as reinforced con-crete and steel
In the future Keith plans to continue research in the areas of material development with spe-cific applications towards strengthening and rehabilitation of structures Additionally he wouldlike the opportunity to teach at the university level
Keith Kesner works onpart of an exhibit onearthquake engineeringthat will be displayed inthe Ithaca Science Center

displaced more than 200000 people from their homesthroughout an area extending some 50 kilometers from theepicenter Economic losses are estimated to exceed $2 billionThis report describes the types and causes of damage resultingfrom the earthquake and the resulting social and economicimpacts
Hysteretic Models for Cyclic Behavior of DeterioratingInelastic Structuresby MV Sivaselvan and AM Reinhorn 11599 MCEER-99-0018 136 pages $2500
For several years now MCEER has supported research associated with developing nonlineartime history modeling strategies for structural systems An important element of these codesis for the user to have an appreciation of the strengths and weaknesses pitfalls advantagesand disadvantages of the various types of hysteretic models employed In the past users ofvarious nonlinear time history analysis programs have needed to be very adept in assigningvalues for the various parameters that control hysteretic rules as little documentation wasavailable More recently there has been an increased awareness in the use of nonlinear timehistory analysis programs in professional engineering practice Instead of developing betterprograms there is a need to use existing programs in a smarter fashion Therefore thepurpose of this report is (1) to provide a theoretical basis for a range of rule-based piecewiselinear hysteretic models (in Section 2) as well as differential equation-based smooth hystericmodels (in Section 3) and (2) to provide a sound and formal reasoning for the basis of theabove-mentioned models that are founded on the fundamentals of mechanics and theinterrelationship between these various types of models (in Section 4)

Report from the Twelfth World Conference on Earthquake Engineering
Earthquake hazard mitigation specialistsfrom around the world met at the 12th WorldConference on Earthquake EngineeringResearch in New Zealand A scene from theopening ceremony is shown above
On January 30-February 4 2000 over2000 members of the international
earthquake engineering community as-sembled for the Twelfth World Conferenceon Earthquake Engineering (12WCEE) inAuckland New Zealand Many mem-bers of the MCEER community werefeatured participants in this world
forum which is held every four yearsIan Buckle and TT Soong were amongthe eleven specialists of internationalstanding who were selected to presentkeynote speeches In their joint sessionBuckle and Soong addressed the historyand state-of-the art in structural control
MCEER Information Servicersquos DorothyTao hosted the MCEER exhibit which at-tracted many visitors including oldfriends and colleagues She also partici-pated in UB Night where a number ofUB graduates now researchers and pro-fessionals throughout the world ferriedto Devenport Island for an evening ofdinner and socializing
Proceedings from the 12WCEE con-taining 1520 papers are availableon CD-ROM (NZ $225) or as a 15 vol-ume hard-bound set (NZ $1015) Toorder contact Richard Buchanan
Keith Kesner is a PhD candidate at Cornell University and is currently involved in a project entitled ldquoDevelopment of Engineered Cementitious Composite Materials for SeismicStrengthening and Retrofitrdquo Dr Sarah Billington is his advisor and his expected graduationdate is May 2002 The project is directed towards the development of cementitious compositematerials that exhibit a ldquopseudo strain hardeningrdquo response in tension It is believed that thesematerials have excellent potential for seismic strengthening and rehabilitation applicationsDevelopment of these materials will require laboratory testing to establish fundamental be-havior characteristics and additional testing to verify the performance of components madewith the composite materials Concurrent with the laboratory testingmaterial models will be developed to allow for finite element basedsimulations of the material performance in structural models
According to Keith ldquoThis research represents a transition in the field ofstructural engineering from the use of traditional materials such as re-
inforced concrete and steel to materials with engineered performance characteristics This isone of the many facets of the project that is exciting to merdquo
This project fits well into MCEERrsquos mission to develop new and emerging materials that havepotential for use in seismic rehabilitation of structures These newer materials may possesssignificant advantages over conventional civil engineering materials such as reinforced con-crete and steel
In the future Keith plans to continue research in the areas of material development with spe-cific applications towards strengthening and rehabilitation of structures Additionally he wouldlike the opportunity to teach at the university level

Hysteretic Models for Cyclic Behavior of DeterioratingInelastic Structuresby MV Sivaselvan and AM Reinhorn 11599 MCEER-99-0018 136 pages $2500
For several years now MCEER has supported research associated with developing nonlineartime history modeling strategies for structural systems An important element of these codesis for the user to have an appreciation of the strengths and weaknesses pitfalls advantagesand disadvantages of the various types of hysteretic models employed In the past users ofvarious nonlinear time history analysis programs have needed to be very adept in assigningvalues for the various parameters that control hysteretic rules as little documentation wasavailable More recently there has been an increased awareness in the use of nonlinear timehistory analysis programs in professional engineering practice Instead of developing betterprograms there is a need to use existing programs in a smarter fashion Therefore thepurpose of this report is (1) to provide a theoretical basis for a range of rule-based piecewiselinear hysteretic models (in Section 2) as well as differential equation-based smooth hystericmodels (in Section 3) and (2) to provide a sound and formal reasoning for the basis of theabove-mentioned models that are founded on the fundamentals of mechanics and theinterrelationship between these various types of models (in Section 4)

For several years now MCEER has supported research associated with developing nonlineartime history modeling strategies for structural systems An important element of these codesis for the user to have an appreciation of the strengths and weaknesses pitfalls advantagesand disadvantages of the various types of hysteretic models employed In the past users ofvarious nonlinear time history analysis programs have needed to be very adept in assigningvalues for the various parameters that control hysteretic rules as little documentation wasavailable More recently there has been an increased awareness in the use of nonlinear timehistory analysis programs in professional engineering practice Instead of developing betterprograms there is a need to use existing programs in a smarter fashion Therefore thepurpose of this report is (1) to provide a theoretical basis for a range of rule-based piecewiselinear hysteretic models (in Section 2) as well as differential equation-based smooth hystericmodels (in Section 3) and (2) to provide a sound and formal reasoning for the basis of theabove-mentioned models that are founded on the fundamentals of mechanics and theinterrelationship between these various types of models (in Section 4)

Report from the Twelfth World Conference on Earthquake Engineering
Earthquake hazard mitigation specialistsfrom around the world met at the 12th WorldConference on Earthquake EngineeringResearch in New Zealand A scene from theopening ceremony is shown above
On January 30-February 4 2000 over2000 members of the international
earthquake engineering community as-sembled for the Twelfth World Conferenceon Earthquake Engineering (12WCEE) inAuckland New Zealand Many mem-bers of the MCEER community werefeatured participants in this world
forum which is held every four yearsIan Buckle and TT Soong were amongthe eleven specialists of internationalstanding who were selected to presentkeynote speeches In their joint sessionBuckle and Soong addressed the historyand state-of-the art in structural control
MCEER Information Servicersquos DorothyTao hosted the MCEER exhibit which at-tracted many visitors including oldfriends and colleagues She also partici-pated in UB Night where a number ofUB graduates now researchers and pro-fessionals throughout the world ferriedto Devenport Island for an evening ofdinner and socializing
Proceedings from the 12WCEE con-taining 1520 papers are availableon CD-ROM (NZ $225) or as a 15 vol-ume hard-bound set (NZ $1015) Toorder contact Richard Buchanan
Keith Kesner is a PhD candidate at Cornell University and is currently involved in a project entitled ldquoDevelopment of Engineered Cementitious Composite Materials for SeismicStrengthening and Retrofitrdquo Dr Sarah Billington is his advisor and his expected graduationdate is May 2002 The project is directed towards the development of cementitious compositematerials that exhibit a ldquopseudo strain hardeningrdquo response in tension It is believed that thesematerials have excellent potential for seismic strengthening and rehabilitation applicationsDevelopment of these materials will require laboratory testing to establish fundamental be-havior characteristics and additional testing to verify the performance of components madewith the composite materials Concurrent with the laboratory testingmaterial models will be developed to allow for finite element basedsimulations of the material performance in structural models
According to Keith ldquoThis research represents a transition in the field ofstructural engineering from the use of traditional materials such as re-
inforced concrete and steel to materials with engineered performance characteristics This isone of the many facets of the project that is exciting to merdquo
This project fits well into MCEERrsquos mission to develop new and emerging materials that havepotential for use in seismic rehabilitation of structures These newer materials may possesssignificant advantages over conventional civil engineering materials such as reinforced con-crete and steel
In the future Keith plans to continue research in the areas of material development with spe-cific applications towards strengthening and rehabilitation of structures Additionally he wouldlike the opportunity to teach at the university level
Keith Kesner works onpart of an exhibit onearthquake engineeringthat will be displayed inthe Ithaca Science Center
The Student Spotlightis a new column dev-eloped to introduceour many student re-searchers and to high-light their current re-search work We planto feature brief profileson one or two stu-dents in each issue

This report deals with the problem of establishing upper and lower bound values ofproperties of seismic isolation bearings for use in the analysis and design of seismicallyisolated bridges These bounding values of properties are determined by using systemproperty modification factors or l-factors On the basis of experimental results and anunderstanding of the basic behavior of seismic isolation bearings l-factor values arepresented for several of these properties including the effects of aging contamination traveltemperature and scragging for selected sliding interfaces and elastomeric bearings Theconcepts presented and the values of the l-factors represent the basis on which boundinganalysis is described in the new 1999 AASHTO Guide Specifications for Seismic Isolation Design
Proceedings of the MCEER Workshop on Ground MotionMethodologies for the Eastern United Statesedited by N Abrahamson and A Becker 81199 MCEER-99-0016 113 pages $2500
In October 1997 MCEER and FHWA sponsored a two day workshop Ground MotionMethodologies for the Eastern United States to evaluate ground motion modeling methodsapplicable in the eastern US The intent of the workshop was to evaluate the state-of-the-artfor strong ground motion prediction and the variability of time histories from differentmodeling methods and to introduce the participants to the concept of formal modelvalidation and application to develop synthetic motionsThe focus was on responding to the user communityrsquos needto evaluate the credibility of synthetic time historiesdeveloped for specific projects and the lack of criteria onwhich to base these evaluations Eight scientists contributedto this effort The proceedings contain a description of theground motion modeling methods model validation andestimation of variability scenario event ground motions anda discussion of the results The results from these studiescan be downloaded in PDF format from the publicationssection of MCEERrsquos web site at httpmceerbuffaloedupublicationsreportsdocs99-0016appendiceshtml A summaryof the workshop is provided at httpmceerbuffaloedupublicationsreportsdocs99-0016defaulthtml

Earthquake CentersAttend NSF-ERCAnnual Meeting
For the first time as part of the NSFdivision of Engineering Education
and Centers (EEC) MCEER MAE andPEER were invited to the EngineeringResearch Center (ERC) Annual MeetingChaired by NSF Program Leader LynnPreston the November 1999 meeting fea-tured special sessions on strategicplanning for research ERC achievementsand performance measurements andhighlighted accomplishments industrypartnerships and educational programsA highlight of the meeting was the in-troduction of newly-designated ERCrsquos
Prior to the meeting a day-long studentretreat was conducted to allow studentparticipants of ERC Student LeadershipCouncils (SLCs) to exchange experiencesand ideas SLCs consist of students whoreceive ERC support and are designedto immerse students more completely inthe ERC research experience and cultureA poster session organized by the stu-dents demonstrated the extent of theirresearch involvement MCEER was rep-resented at the meeting and postersession by doctoral candidate NataliSigaher Department of Civil Structuraland Environmental Engineering Univer-sity at Buffalo
University at Buffalo doctoral candidateNatali Sigaher presented MCEER researchwork at a poster session during the NSF-ERC Annual Meeting

Quindiacuteo Colombia Earthquake of January 25 1999Reconnaissance Reportby AP Asfura and PJ Flores 10499 MCEER-99-0017 68 pages $2500
At 1319 local time (1819 GMT) on Monday January 25 1999 anearthquake with magnitude 62 on the Richter scale occurred in thewestern part of Colombia The earthquake caused approximately 1200deaths and 5000 injuries damaged or destroyed 50000 structures and
displaced more than 200000 people from their homesthroughout an area extending some 50 kilometers from theepicenter Economic losses are estimated to exceed $2 billionThis report describes the types and causes of damage resultingfrom the earthquake and the resulting social and economicimpacts
Hysteretic Models for Cyclic Behavior of DeterioratingInelastic Structuresby MV Sivaselvan and AM Reinhorn 11599 MCEER-99-0018 136 pages $2500
For several years now MCEER has supported research associated with developing nonlineartime history modeling strategies for structural systems An important element of these codesis for the user to have an appreciation of the strengths and weaknesses pitfalls advantagesand disadvantages of the various types of hysteretic models employed In the past users ofvarious nonlinear time history analysis programs have needed to be very adept in assigningvalues for the various parameters that control hysteretic rules as little documentation wasavailable More recently there has been an increased awareness in the use of nonlinear timehistory analysis programs in professional engineering practice Instead of developing betterprograms there is a need to use existing programs in a smarter fashion Therefore thepurpose of this report is (1) to provide a theoretical basis for a range of rule-based piecewiselinear hysteretic models (in Section 2) as well as differential equation-based smooth hystericmodels (in Section 3) and (2) to provide a sound and formal reasoning for the basis of theabove-mentioned models that are founded on the fundamentals of mechanics and theinterrelationship between these various types of models (in Section 4)
