| 摘 要： | 基于再生混凝土低矮剪力墙抗震性能试验结果及分析的基础上,通过非线性有限元软件MSC.Marc(2011)对6片再生混凝土低矮剪力墙进行了数值模拟并得到了构件的破坏形态、滞回曲线、骨架曲线及各墙体的初始刚度、极限承载力、位移延性系数等.有限元模型中墙体及钢筋采用分离式有限元模型进行建模,其尺寸均按照试验实际尺寸确定.数值模拟结果与试验结果对比分析表明应用有限元软件MSC.Marc(2011)可对再生混凝土低矮剪力墙的设计及抗震性能研究提供参考和依据.

| Abstract: | Based on the experimental study and analysis on seismic behavior of squat recycled concrete shear walls, six squat recycled concrete shear walls are simulated and the results of failure patterns, hysteresis curves, skeleton curves, initial stiffness, load_carrying capacities, displacement ductility factors are got through the nonlinear finite element software MSC. Marc (2011). The wall and rebars in the finite element model adopt separate finite element model for modeling, and their dimensions are determined according to that actual sizes in the test. Comparation between simulation results and test results shows that the application of finite element software MSC. Marc (2011) can provide reference and basis for the design and research on seismic behavior of squat recycled concrete shear wall. |
