EERI 2014 Technical Seminar Series – a Review

towers

With about 240 participants, the 2014 EERI Technical Seminar Series focusing on the state of the practice for Performance Based Seismic Design (PBD) of Tall Buildings was a great success.

For the last decade, engineers in major cities along the West Coast have taken advantage of performance based design concepts to achieve structural designs of tall buildings that are not in strict compliance with the International Building Code prescriptive provisions. The seminar speakers, all at the forefront of the evolution of performance based design procedures, presented their experiences and state-of-the art-practice in their individual areas of specialization.

The presentations from this seminar series are now available for purchase from the EERI Knowledge Center and Online Store: www.eeri.org/products-page/technical-seminars

The seminar presentations gave a broad picture of the state of practice for the performance based design of tall buildings. Ron Hamburger (M. EERI, 1988) began with an overview of the history of PBD. Farzad Naeim (M. EERI, 1983) and Jack Moehle (M. EERI, 1981) followed with a presentation on the use of guidelines published by the Pacific Earthquake Engineering Research Center (PEER) and the Los Angeles Tall Buildings Structural Design Council (LATBSDC).

The focus then turned to seismological and geotechnical considerations with a presentation titled “Using Ground Motions and SFSI,” by Marshall Lew (M. EERI, 1978) and Jonathan Stewart (M. EERI, 1994) on the development of seismic demands in the form of both response spectra and ground motions for long period structures. Gregory Deierlein (M. EERI, 1989) covered structural analysis and modeling procedures used in PBD, after which two case studies of Tall Buildings were presented: John Hooper (M. EERI, 1987) presented Concrete Building Design, using the Salesforce Tower design as the case study. Leonard Joseph and Nabih Youssef (M. EERI, 1987) both presented Steel and Composite Construction design, focusing respectively on the case studies of Wilshire Grand Tower in Los Angeles and the Los Angeles Convention Center Hotel. Following the presentation of the case studies, Farzad Naeim and Jack Moehle gave an overview of the lessons learned from the Peer Review process in tall building design. Ron Hamburger concluded the talks with a presentation on the future directions of PBD, FEMA (ATC) 58, and moving present practice to the next level.

The technical seminar series was sponsored the Federal Emergency Management Agency (FEMA). Co-sponsorship was provided by ASCE Metropolitan Los Angeles Branch, EERI Regional Chapters (Northern California, Southern California, and Washington), Seattle ASCE, Structural Engineers Association of Washington (Seattle), Structural Engineers Association of Oregon, and the Structural Engineers Association of Southern California.
