摘要
本文使用结构分析有限元软件SAP2000模拟已有试验。整理了几位科研工作者在各自文献中数值模拟梯段板的方法,分别放入模型中,力图找出比较合适的模拟梯段板方法。文中采用Pushover分析方法得出带有不同方式模拟梯段板的模型数据,与试验结果进行对比。结果分析表明:在进行弹性分析时,结构中的梯段板可以用壳单元进行模拟。在进行弹塑性分析时,结构中的梯段板可以用同尺寸柱杆模拟,并沿杆长方向每隔距离0.05倍杆长的位置布置自定义的轴力和双向弯矩耦合的铰(P-M-M铰)。
This article uses the finite element software SAP2000 for structure analysis to simulate a test.By collecting the method of numerical simulation for staircase boards of several scientists in the respective literature and putting these method in model,the most suitable simulated method of staircase board was tried to find out.Pushover analysis method is used to draw data with simulate staircase board model in different ways,and compared with the experimental results.The results show that the structure of the staircases boards can be simulated by using shell elements in linear analysis.During nonlinear analysis,the staircase board of the structure can be simulated by the same size pole and custom axial force and biaxial moment every distance of 0.05 times the rod length position arranged along the direction of the length of the rod coupling hinge(P-M-M hinge).
