摘要
提出的钢筋混凝土带暗支撑剪力墙是在普通带竖缝剪力墙板配筋基础上，对各板条加配Ｘ型支撑钢筋后形成的．它仍采用竖缝提高剪力墙板的延性，并用竖缝处的砼键控制初始刚度，同时增设 Ｘ型暗支撑以提高后期的抗震承载力．这种新型剪力墙具有良好的抗震性能，并已用于工程．通过低周反复荷载作用下的结构试验研究，对这种新型剪力墙的 刚度、承载力、延性、破坏特征等进行了分析．在此基础上，建立了力学计算模型与方法， 理论计算的结果与实测结果符合良好．
R. C. shear wall with concealed bracings is presented. Based on reinforcements of ordinary shear wall plate with vertical joint, the new-type wall adds reinforcements of X-shaped bracings to laths. The ductility of shear plate is improved through vertical jiont, the initial rigidity is controlled through R. C. key in vertical joint, the later aseismic bearing capacity of structure is raised through setting up X-shaped concealed bracings. The new-type shear wall has good aseismic behavior, and it has been used in engineering. Through testing tesearch of the new-type shear wall at low cyclic loading, rigidity, bearing capacity, uctility, failure characteristic are analysised. The mechanical model and calculating method are founded. The theoretical calculating results conform well with real measuring ones.
