Whereas countless research studies have focused on the performance of reinforced concrete and steel structures, heavy timber structures have received very little attention. This study focuses on the multi-hazard performance of timber pile bridge substructure. Most timber pile bridges currently in service in the United States were constructed in the 1950’s and 60’s based on now outdated design methods. Given their age and susceptibility to deterioration, the performance of timber pile bridges under extreme loading scenarios is a concern. Wrapping timber piles with fiber reinforced polymer (FRP) composites has been shown to significantly improve the strength and durability of deteriorated timber piles. In this study, a step-wise analysis method is used to subject a typical timber pile bridge substructure to a combination of earthquake and tsunami loading. The performance of unretrofitted and FRP retrofitted timber piles are compared. Being able to simulate and predict the response and failure mechanisms in these extreme natural hazards will allow for safer new designs and effective retrofits for existing structures.
