摘要
利用ABAQUS软件对试验原型结构的试验进行模拟,并根据试验原型结构的试验结果对ABAQUS软件中的模型参数进行修正.在此基础上创建5个体积配箍率不同的框架柱,在固定轴向荷载和低周反复荷载作用下进行模拟试验;通过分析构件的骨架曲线和滞回曲线,找出体积配箍率对轴压比超限框架柱抗震性能的影响规律.研究结果表明:随着体积配箍率的增加,框架柱荷载-位移曲线愈加饱满;位移延性系数和极限位移得到显著提高,并具有良好的延性及耗能能力.
Using software ABAQUS,the test of prototype structure is simulated and the model parameters of ABAQUS are modified according to the test result of the prototype structure.Then,5 framed columns with different volume stirrup ratio are created and tested under fixed axial loads and low cyclic loads.The pattern of the influence of volume stirrup ratio on anti-seismic performance of the framed column with excessive axial compression ratios is found by means of analysis of the skeleton curves and hysteretic curve of the framed column.The investigation result shows that with the increase in the volume stirrup ratio,the load-displacement curves of the framed column will become plumper,the displacement extension ratio and ultimate displacement will improve significantly,and a good extension and energy dissipation capacity will obtain.
