【摘要】：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。
[Abstract]:The pseudo-static test and finite element analysis of frame-embedded wall structure are carried out, the bearing capacity and energy dissipation capacity are studied, and the friction coefficient between the wall plate and the column is discussed. The results show that the hysteretic curve of frame-embedded wall structure is full in shape and shows good ductility and energy dissipation ability. The lateral stiffness and bearing capacity of the frame structure are improved obviously after the wall is embedded, and before the structure yielding (normal service condition, there is no obvious seam between the walls, after yielding, the wall plate is staggered obviously, the wall board and the wall board, the wall board and the wall board, the wall board and the wall board, the wall board and the wall board, The joint width can be reduced by increasing the friction coefficient between the wall board and the column, and the bearing capacity of the frame-embedded wall structure can be improved by increasing the axial compression ratio of the column to a certain range. Because the embedded wall plate is not in a straight line with the axis of the column, the frame column bears a certain amount of torque. In the actual engineering design, the torsional reinforcement of the column should be increased or the design of the torsional reinforcement of the column should be carried out.
