Introduction: Performance-based
earthquake engineering (PBEE) methodology has been a rigorous product of
the Pacific Earthquake Engineering Research Center (PEER). The final
output of the methodology is a detailed quantification of performance
using metrics that are of immediate use to engineers and other
stakeholders; a drawback of the methodology is that it requires much data
and effort to arrive at a final performance statement. PEER is
undertaking a study to promote development of a simplified PBEE
methodology, and will use a simplified building model to demonstrate its
application. This example will illustrate PBEE as conceptualized by PEER
using applications to various steel framing systems. This includes
conventional concentrically braced frame (SCBF), moment resisting frame (SMRF)
and concentrically braced frame (SEBF)
found near the UCB campus. Ground motions that represent the hazard at the
site will be selected and a series of nonlinear dynamic analysis for the
ensemble of ground motions will be analyzed. In essence a Monte-Carlo
analysis to obtain distributions of engineering demand parameters (EDPs)
will be studied. Given the distribution of the EDPs, distributions of
damage measures (DM) and decision measures (DV) will be developed that
will illustrate the use of PBEE in selecting a structural system among
several competing systems. Do not hesitate to contact should you have any questions. |
