Deformation and energy-based seismic damage evaluation of Steel reinforced concrete and reinforced concrete Piers

摘要

The method of MMCP (modified modal cyclic pushover) which can reflect the dual criterion of deformation and energy was used to make an assessment on seismic performances of the steel reinforced concrete piers and reinforced concrete bridge piers. Then the calculated results were analyzed comparing with the results of dynamic time historical analysis and quasi static test. To some extent, the MMCP analysis may simulate the seismic action. In addition, the MMCP method can also be associated with the design response spectrum, making the evaluation results to be reliable and safe. The results indicate that MMCP applicability analysis also exists in the steel reinforced concrete structure, and the seismic capacity of steel reinforced concrete bridge piers is better than reinforced concrete bridge piers.
