Multiple-Hazard Design Principles for Highway Bridges

Project Information

Project ID: 
FHWA-PROJ-08-0013
Project Abstract: 

Safety is one of the highest priorities among all design considerations of highway bridges. Extreme hazard loadings, such as earthquake, flooding, vessel collision, scouring, wind, and traffic overload have caused a significant number of bridge failures nationwide. Developing solutions to effectively deal with unexpected hazard loadings has been a significant challenge facing the bridge engineering community. Under the current American Association of State Highway and Transportation Officials Load Resistance Factor Design Bridge Design Specifications, design safety of a highway bridge is measured by a uniform reliability. The design of individual natural hazard loadings, such as earthquake, is considered independently and is not consistent with other natural hazards or service loadings. This project seeks the solution of developing the bridge design principles/criteria that will be consistency in all natural hazards either an individual or a combined event.

Goals

This study will develop a fundamental design methodology and criteria to evaluate and compare the impact of multiple hazards on highway bridges.
