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.The PC-based tool lets engineers conduct PBEE analysis
Arch dams, classically curved monoliths situated in narrow valleys, are not as common as other types of dams, such as embankment dams and gravity dams. ENR takes a look at some of the biggest arch dams in the world, both completed and under construction.
