PBE Application Update (V3.3.0)

March 8, 2024

The PBE Application is an open-source software tool that simulates the impact of a natural hazard event on a building or other structure. The impact is quantified in a probabilistic approach using the pelicun damage and loss assessment engine. Structural response simulations with commercial tools and non-seismic hazards are supported by allowing users to import external response data. Custom user-defined models and calculation methodologies are also supported. Damage and loss results can be used in the integrated REDi functional recovery simulation tool to simulate the repair process of a building.

The primary improvement in PBE Version 3.3.0 comes from the updates in the pelicun engine. A comprehensive set of tests and corresponding code enhancements substantially improve the robustness and efficiency of the damage and loss simulations. Download PBE (V3.3.0) to take advantage of these features:

  • Enhanced Flexibility: Users can now define multiple instances of the same component type in a single location and direction within the asset model. This makes it easier to handle buildings with multiple tenants, and performance groups with specific, non-uniform component block sizes.
  • Improved clarity: output files include units and are updated to the latest SimCenter format. Error messages provide more informative feedback to assist the user with troubleshooting.

A high-level, two-page overview of the PBE Application can be viewed from the website.
