核心型钢混凝土柱抗震性能试验及数值模拟
Experimental Investigation and Numerical Simulation of Seismic Behavior of CSRC Columns
摘要
Abstract
One reinforced concrete (RC) column and eight core steel reinforced concrete (CSRC) columns are tested under low-cycle reversed load to investigate the effect of core steel ratio and axial compression ratio to the seismic behaviors of specimens. It is indicated that the seismic behaviors of specimens are remarkably improved with the increase of core steel ratio. Nonlinear numerical simulation of CSRC columns is carried out with finite element method software ADINA,the calculation results agree well with the test results, such as the skeleton curves, stress and strain distributions, the development of cracks.关键词
