Task 12 – Quantification of seismic performance levels of tall buildings

Task description – The task seeks to identify the benefits and costs of designing tall buildings to alternative performance levels, and aims to provide data that will help code writers and local jurisdictions address the question of whether alternative performance objectives are appropriate and cost-beneficial for tall buildings. In this project, practitioners with experience in tall building seismic design have developed conceptual designs of three different tall buildings, each designed by three different design procedures, for a total of nine designs. PEER researchers at UC Berkeley, UC Irvine, and UCLA are analyzing these design variations to quantify construction costs, seismic performance, and post-earthquake capital losses.

Lead investigator – Jack Moehle, PEER

Team members –Researchers Jack Moehle (UCB), Yousef Bozorgnia (UCB), John Wallace (UCLA), Farzin Zareian (UCI), and Tony Yang (UBC); practicing engineers at Magnusson Klemencic Associates (Seattle), Simpson-Gumpertz & Heger (San Francisco), and Englekirk Associates (Los Angeles); and cost or loss estimator RMS.
