The PBE Application (PBE App) is an open-source software that provides researchers a tool to assess the performance of a building in an earthquake scenario. The application focuses on quantifying building performance through decision variables. Given that the properties of the buildings and the earthquake events are not known exactly, and that the simulation software and the user make simplifying assumptions in the numerical modeling of the structure, the estimate response of the structure already exhibits significant variability. Such response can be estimated using our EE-UQ Application. The PBE App builds on the EE-UQ App and uses its response estimates to assess the damage to building components and the consequences of such damage.
