混凝土叠合承重墙抗震性能的试验研究

通过对两种不同构造形式的混凝土叠合承重墙在低周反复荷载作用下的试验,研究了混凝土叠合承重墙的受力全过程、开裂部位、裂缝发展情况以及破坏形态,分析了墙体的滞回特性、延性、耗能能力,刚度退化曲线等抗震性能。同时,考察了预制板与隐形框架共同工作的性能。试验表明:混凝土叠合承重墙自开始加载到最终破坏,预制板和隐形框架可很好地协同工作,两者可形成两道抗震设防,墙体具有较大的承载力、良好的抗震性能和延性。另外,有横筋拉接的墙体的承载能力相对较大,并具有较好的延性。

Experimental Study on Seismic Behavior of Concrete Composite Bearing Wall

Based on the low cyclic reversed lateral loading tests of two groups of concrete composite bearing wall, the behavior such as deformation process,failure mechanism,hysteretic characteristic,ductility,energy-dissipation ca- pacity and curve of stiffness degradation was studied.In the mean time,working performance of the prefabricated board and frame were investigated.The test results reveal that from the beginning to the end,the prefabricated board and frame could work in coordination very well,they could form two seismic fortifications.It was shown that the wall had good loud-carrying capacity,seismic behavior and ductility.Besides,the loud-carrying capacity and ductility of the wall connected with horizontal muscle was better than the other group.
