Bridge analysis software to model the interaction of soil, foundation and structure in simulated earthquakes weighs a host of variables to achieve results. Making such a complex process user-friendly is a challenge.
BridgePBEE, a graphical pre- and post-processor performance-based earthquake engineering (PBEE) analysis tool, aspires to do just that. The beta version is available for free download from the University of California, Berkeley's Pacific Earthquake Engineering Research (PEER) Center.
