Estimating Inelastic Displacement Demands for Bridges Under Seismic Load

The objective of this research is to develop robust procedures for calculation of inelastic displacement demands in bridges while also providing guidance on how to best model damping in non-linear response history analysis. Based upon observations developed during the conduct of NCHRP 12-106, current methods for evaluating displacement demands may be substantially non-conservative, leading to bridges that may sustain much higher displacements (and hence damage) than what was expected during the design phase. Implementation of PBSD requires accurate estimation of displacement demand, making this vitally important to the engineering community.
