Article Preview

Energy-based modal pushover analysis method has been proved to be an appropriate approach to perform seismic analysis for structures whose high mode effect is not negligible. It directly establishes the capacity spectrum based on energy increments, which corrects the deficiency of conventional modal pushover method that the capacity curve would not be unique or even be retorted while the base shear-top displacement curve is established with respect to different reference nodes of the structure. In this paper, a continuous rigid frame bridge with tall piers in seismic zone is analyzed with EMPA method. The results showed that EMPA is more adaptable than conventional methods, and the seismic performance of the bridge can satisfy the demand of the design code.
