摘要:
利用三维非线性分析程序CANNY中的纤维模型模拟墙肢、单轴弹簧模型模拟连梁,对钢筋混凝土联肢剪力墙进行了弹塑性分析; 在与试验结果进行对比分析的基础上,选取了用于钢筋混凝土剪力墙非线性分析的三线型骨架滞回模型和合适材料的应力-应变关系进行建模; 通过数值计算分析了轴压比、墙体分布钢筋配筋率、边缘构件配筋率、连梁纵筋配筋率对钢筋混凝土联肢剪力墙的承载力、延性、破坏形态等的影响。结果表明:轴压比、墙体分布钢筋配筋率、边缘构件配筋率对钢筋混凝土联肢剪力墙的受力性能影响较大,连梁的纵筋配筋率影响较小; 所选模型具有有效性。
Abstract:
The fiber model in 3-dimensional nonlinear analysis program CANNY was used to simulate walls, and the uniaxial spring model was adopted to simulate beams. Elasto-plastic analysis of reinforced concrete coupled shear wall was carried out. Based on the comparison analysis with test result, the trilinear skeleton hysteresis model and proper material stress-strain relations were selected for simulating reinforced concrete coupled shear wall model. Through numerical calculations, the influences of design parameters, such as axial compression ratio, reinforcement ratio of steel bars for wall distribution, reinforcement ratio of longitudinal bars for beams as well as reinforcement ratios of marginal members on bearing capacity, ductility, failure shape for reinforced concrete coupled shear walls were considered. The results indicate that the axial compression ratio, reinforcement ratio of steel bars for wall distribution, reinforcements of marginal members significantly affect the mechanical behavior of reinforced concrete coupled shear walls, and reinforcement ratio of longitudinal bars for beams less affect the behavior; the analysis model is proved to be effective.
