| 摘 要： | 在低周反复荷载作用下,对1个钢筋混凝土柱和8个核心型钢混凝土柱进行试验,研究核心型钢配钢率和轴压比对试件抗震性能的影响.研究结果表明,试件抗震性能随着核心型钢配钢率的增加得到显著改善.采用有限元软件ADINA对试件进行非线性有限元全过程分析,计算得到的试件骨架曲线、应力应变分布和裂缝发展情况与试验结果吻合良好.

| 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 tes... |
