This presentation summarizes the benefits and challenges of implementing performance-based seismic design (PBSD) for the concrete buildings of the Lower Sproul Plaza Redevelopment Project in one of the busiest areas of UC Berkeley campus. The project included new construction of Eshleman Hall and the additions to Martin Luther King (MLK) Hall, and the seismic retrofit of the existing MLK Hall as a result of the expansion. The peer-reviewed PBSD implemented three-dimensional nonlinear response history analyses at two levels of seismic hazard. The analytical simulations using pairs of near-fault ground motions, scaled to match the site specific spectrum, were intended to establish the expected seismic behavior of the buildings under rare and frequent earthquakes.
