| 摘 要： | 采用MSC.Marc建立SRC剪力墙有限元分析模型,通过对5片SRC剪力墙试件的非线性有限元分析,验证了有限元模型的合理性和可靠性。对轴压比和钢骨配钢率对SRC剪力墙抗震性能的影响进行了参数分析。SRC剪力墙的承载能力随轴压比的增加而提高,变形能力随轴压比的增大而降低;承载能力随配钢率的增加而提高,变形能力也有所提高,但轴压比较高时不明显。

| Abstract: | Nonlinear finite element(FE) analysis of steel reinforced concrete(SRC) shear wall was performed using software MSC.Marc.The rationality and reliability of the FE model was verified through the comparison between the FE analysis results and the experimental results of the five SRC shear wall specimens.Based on the proposed FE model,parametric analysis was carried out to study the effect of the axial compression ratio and steel ratio on seismic behavior of SRC shear walls.The analysis results showed that the... |
