A Performance Based Approach for Loading Definition of Heavy Vehicle Impact Events
Brief Description of Research
Based on bridge failure data compiled by the New York State Department of Transportation, collision, both caused by vessels and vehicles, is the second leading cause of bridge failures after hydraulic. The current AASHTO-LRFD (2012) specification recommends designing a bridge pier vulnerable to vehicular impacts for an equivalent static force of 600 kips (2,670 kN) applied in a horizontal plane at a distance of 5.0 feet above the ground level. This research studies a performance based approach for designing a bridge pier subject to impact by a tractor-semi-trailer weighing up to 80,000 lb based on an extensive experimental and computational investigation.

Contribution of the HPC in your research
Running simulations of vehicular impact on a normal PC is very time-consuming. With the help of HPC, the computation time for each case is greatly reduced from weeks to one or two days.
