摘要:
基于ABAQUS有限元分析软件,建立了钢筋混凝土(RC)框架砌体填充墙结构非线性有限元模型,并对框架砌体填充墙结构破坏全过程进行了模拟,验证了所建模型的可靠性。建立了200 mm厚的填充墙模型,分析不同开洞率、开洞位置、开洞形状对RC框架填充墙结构纵墙平面外抗震性能的影响,根据填充墙的等效应力云图和等效塑性应变云图,对模型的受力情况及填充墙的破坏形式进行分析,总结了开洞对填充墙平面外受力性能的影响。结果表明:在开洞率为10%,20%,30%,40%的框架填充墙模型中,开洞率越小,填充墙的平面外破坏就越接近脆性破坏; 开洞率为10%的填充墙框架尺寸不变时,开洞靠近框架柱开设,填充墙出现裂缝的层间位移角更小,发展更迅速; 开洞率为20%的填充墙框架尺寸不变时,开洞的高宽比越小,填充墙的边界裂缝和水平横缝出现的层间位移角越大。
Abstract:
Based on ABAQUS finite element analysis software, the nonlinear finite element model of reinforced concrete frame masonry infilled wall structure was established, the whole failure process of frame masonry infilled wall was simulated, and the reliability of the model was verified. A 200 mm thick infilled wall model was established to analyze the influence of different opening ratio, opening position and opening shape on the out-of-plane seismic performance of longitudinal wall of RC frame infilled wall structure. According to the equivalent stress nephogram and equivalent plastic strain nephogram of the infilled wall, the stress condition of the model and the failure mode of the infilled wall were analyzed. The influence of opening on the out-of-plane mechanical properties of infilled walls was summarized. The results show that in the frame infilled wall model with 10%, 20%, 30% and 40% opening ratios, the smaller the opening rate is, the closer the out-of-plane failure of infilled wall will be the brittle failure. When the frame size of the infilled wall with 10% opening ratio remains unchanged, the closer the opening is to the frame column, the smaller the interlayer displacement angle of the infilled wall with cracks appears, and the development is more rapid. When the frame size of infilled wall with opening ratio of 20% remains unchanged, the smaller the ratio of height to width of the opening is, the greater the interlayer displacement angles of boundary cracks and horizontal transverse joints of infilled wall are.
