12 - Assessing seismic risks for new and existing buildings using performance-based earthquake engineering (PBEE) methodology

Abstract

Performance-based earthquake engineering (PBEE) aims to quantify performance of facilities using metrics that are of immediate use to both engineers and stakeholders. A rigorous yet practical implementation of a PBEE methodology is presented. The methodology considers seismic hazard, structural response, resulting damage, and repair costs associated with restoring the building to its original condition, using a fully consistent, probabilistic analysis of the associated parts of the problem. The methodology is demonstrated using an actual high-rise building designed using three design approaches. The proposed procedure is consistent with common building design, construction, and analysis practices such that it can be readily adopted in earthquake engineering practice today.
