Abstract:Increases in the rate of seismicity in Texas and in neighboring states since 2008 motivated recent Texas Department of Transportation (TxDOT) research (0-6916), which characterized seismic hazards and bridge fragility, or likelihood of damage based on ground shaking intensity, in Texas; these factors were combined to develop a post-earthquake inspection plan. In this implementation project (5-6916-01), these research outcomes were incorporated into a conversion software—the TexasBridgeDataConverter.exe—to facilitate use of ShakeCast, the software developed by the U.S. Geological Survey (USGS) to automate the process of identifying and prioritizing post-earthquake inspection needs. The research team (1) developed a new software for updating the TxDOT bridge inventory and associated fragility functions in ShakeCast; (2) incorporated updated Vs30 maps into USGS ShakeMaps, which are used to estimate ground shaking levels in the ShakeCast software; and (3) created an operating manual and conducted a virtual workshop for TxDOT personnel on how to use ShakeCast and the researcher-developed software for inventory updating.
