A primary goal of seismic design requirements of bu ilding codes is to protect the life safety of building inhabitants during extreme earthquakes, which requires that the likelihood of structural collapse be at an acceptably low level. However, building codes and standards are empirical in nature; this results in the collapse safety of new buildings not yet being well understood.
In this research, we develop the tools and methods to quantitatively assess the collapse risk of reinforced concrete (RC) special moment frame (SMF) buildings. This primarily includes treatment of ground motions, element model calib ration, and treatment of structural modeling uncertainties.
