摘要:
采用有限元方法对钢筋混凝土（RC）带翼缘剪力墙的全过程受力状态进行了数值模拟，在验证模型有效性的基础上，分析了带翼缘剪力墙在地震荷载作用下的受力机理和破坏过程，并分别就翼缘受压和翼缘受拉方向，研究了加载过程中钢筋和混凝土的应力应变分布规律，讨论了翼缘中存在的剪力滞后现象，结果表明：当剪力墙达到极限状态时，试件两侧受力纵筋均能达到屈服，翼缘内混凝土只受拉开裂，受压始终未达到峰值压应力，表明翼缘具有良好的受压性能.翼缘截面内的受拉钢筋和受压混凝土应变均呈非线性分布，翼缘截面存在明显的剪力滞后现象，并且剪滞效应随着加载过程不断加剧.
Abstract:
The stress state in whole loading process of reinforced concrete (RC) shear walls with flange was simulated using the finite element method. Based on the verified model, the stress mechanism and failure process of flanged shear walls under earthquake loading were analyzed. The stress and strain distribution of reinforced bar and concrete during loading were studied for the flange in compression and tension respectively, the shear lag effect in flange was discussed as well. The results indicate that the longitudinal reinforcement on both sides of the specimen can reach the yield when shear walls reach the limit state. The concrete in the flange only cracks in tension, but never reaches the peak stress under compression, which indicates that the flange has good compressive properties. The strain of the tension bar and the compressive concrete is nonlinearly distributed along the flange cross section so the shear lag effect is obvious in the flange, and the shear lag effect aggravates with the loading process.
