加气混凝土砌块砌体与构造柱组合墙抗震性能试验
|
摘要
研究了不同开洞情况(无洞口、开窗洞、开门洞)下加气混凝土砌块砌体与构造柱组合墙的抗震性能,通过低周反复荷载拟静力试验,讨论了这3种墙体的破坏形式、滞回曲线、承载能力、变形性能、刚度退化及耗能能力等特性,并比较了开洞情况对墙体上述性能的影响.试验表明,在墙体两端设置的构造柱,对墙体能形成有效的约束,使墙体具有较高的抗震抗剪承载力和开裂后的承载能力储备,在强震下有较好的极限变形能力和良好的耗能性能。研究还表明,墙体的抗剪承载力随着洞口水平截面积的增大而明显降低.
Seismic behavior of composite walls with different opening types( no opening,with a window opening,with a door opening) and made of aerated concrete block masonry and constructional columns was studied in this paper. The failure mode,hysteretic curve,bearing capacity,deformation behavior,stiffness degradation and energy dissipation capacity were disscussed and the effects of opening types on the above mentioned characteristics were compared. Test results show that constructional columns set on both ends of the wall can be effecttive restraints,which will enhance the composite wall's shearing capacity during an earthquake and the bearing capacity after cracking and so that the wall can have better ultimate deformation capacity and energy dissipation capacity. The study also shows that the shearing capacity of the wall is significantly reduced with the increase of cross section area of the opening.
