对框架-嵌入式墙体结构进行了拟静力试验和有限元分析,研究了其承载力和耗能能力,探讨了墙板与柱间摩擦系数、轴压比以及墙板分割块数对结构抗震性能的影响。研究结果表明:框架-嵌入式墙体结构滞回曲线形状较为饱满,表现出良好的延性和耗能能力,且嵌入墙体后明显提高了框架结构的抗侧刚度和承载力;在结构屈服前(正常使用状态),墙板间无明显通缝,屈服后,墙板错动现象明显,墙板与墙板、墙板与底梁间均出现明显的通缝,增加墙板与柱间的摩擦系数,可减小通缝宽度;在一定范围内,增大柱轴压比,可提高框架-嵌入式墙体结构的承载力;由于嵌入墙板与柱轴线不在一直线上,框架柱承受了一定的扭矩,在实际工程设计中,应增加柱的抗扭构造配筋或进行柱抗扭配筋设计。
The pseudo-static test and finite element analysis of the frame-embedded wall structure were carried out. The bearing capacity and energy dissipation capacity of the frame-embedded wall structure were studied. The friction coefficient between the wall plate and the column, the axial compression ratio, Seismic performance impact. The results show that the hysteresis curve of the frame-in-wall structure is relatively full, which shows good ductility and energy dissipation ability. The wall stiffness increases the lateral stiffness and the bearing capacity of the frame structure. (Normal use), no obvious cracks between the wall panels, after yielding, the phenomenon of wall panels staggering obvious wall panels and wall panels, wall and bottom beams were obvious through the seam between the increase of wallboard and column The coefficient of friction can reduce the width of the through-seam; in a certain range, increasing the column axial compression ratio can increase the bearing capacity of the frame-embedded wall structure; because the embedded wallboard and column axis are not in a straight line, A certain torque, in the actual engineering design, should increase the column torsion reinforcement or column design torsion reinforcement.
