Vulnerability of Bridges to Natural Events

Abstract

This project utilized the HAZUS program and ArcGIS to perform vulnerability assessments on the bridges in Puerto Rico After conducting earthquake scenarios, the most probable bridge to experience failure or distress was identified and analyzed It was determined that the HAZUS program and ArcGIS were not fully integrated for different hazard scenarios, and the learning curve in order to use them by novice investigations were steep A more traditional methodology is suggested to identify high risked bridges, such as merging liquefaction, tsunami, landslide and seismic wave maps together in order to identify the bridges that are located in areas of concurrent high natural hazards, being more likely to be affected by such events
