摘要:
为了研究配筋砌块砌体剪力墙的抗震能力,采用约束砌块砌体和约束混凝土作为剪力墙的约束边缘构件以增加延性; 通过对位移延性的计算,得出影响剪力墙位移延性的主要因素有轴压比、形状比、砌体的极限压应变等,并建议了不同约束边缘构件剪力墙的轴压比限值.在此基础上用反应调整系数衡量配筋砌块砌体剪力墙的抗震能力,明确了设置约束边缘构件剪力墙所隐含的抗震能力; 对不同抗震等级剪力墙的反应调整系数与地震动比值进行计算,通过比较得出结论:配筋砌块砌体剪力墙为实现规范预期的抗震设防目标,必须对剪力墙的形状比进行限制.
Abstract:
In order to study the seismic capacity of reinforced-block-masonry shear walls, the confined masonry and the confined concrete are put forward as boundary member material to increase the ductility of shear walls. Through the calculation of displacement ductility, the key factors which influence the displacement ductility of shear walls are obtained, they are axial-compression-ratio, shape ratio, limit compress strain of masonry, etc. The axial-compression-ratio limitation is proposed for masonry walls with different confined boundary members. The response modification factor is introduced to evaluate seismic capacity of the masonry walls, and the seismic capacity of the masonry walls with the suggested confined boundary members is specified. The response modification factor of the masonry walls is compared with ground motion ratio under different seismic level.It is concluded that the shape ratio of the masonry walls must be restricted to meet seismic requirements of China’s codes.
