Numeric Analysis on Seismic Performance of RC Round-ended Piers with HRBF500 Steel Bars
4 RC round-ended piers with HRBF 500 steel bars are analyzed by finite element package ABAQUS under low reversed cyclic loading.In order to check the validity of the FEM analysis, the numerical analyses results of RC round-ended piers with HRBF 500 steel bars are compared with the previous experimental results.It indicates that the analytical results calculated by ABAQUS agree well with the test results.The paper mainly researches the seismic performance, including component ductility, strength and hysteresis dissipation characteristics, of HRBF 500 steel bars applied in High-speed railway piers.The effects of strength of longitudinal reinforcement, axial compression ratio, hoop reinforcement ratio on the seismic behaviors of piers are analyzed.The research results will provide the important data for HRBF 500 steel bars used in bridge pier of high speed railway.
