摘要
通过对六片钢筋煤矸石砼单片剪力墙的试验，研究了在低周反复荷载作用下的不同横向配筋 率，不同剪跨比的剪力墙强度和变形性能．试验表明：轻砼剪力墙的受力性能和破坏形态与普通砼剪力 墙极为相似．配以暗框边柱能提高剪力墙的抗剪强度、位移控制和破坏控制能力．在试验基础上分析了 荷载传递和构件破坏的机理，提出了计算剪力墙抗剪强度公式，其计算结果与试验值吻合较好．最后对 剪力墙滞国特性、延性和刚度退化率作了分析，为工程实际中煤矸石砼剪力墙的应用提供了实验依据。
Six cantilever shear walls with self-combusted gangue reinforced concrete were experimented. The behaviors of strength and deformation were investigated with various shear span ratios and transverse hoops under low cyclic loading. The results show that mechanical properties and failure models of the walls are almost the same as the heavy concrete shear wall's, but the former is greater than the later in the capability of energy dissipation. Embedded columns can increase shear strength as well as control of displacement and failure. Formula evaluating the shear strength of wall is suggested. The calculated results are in good agreement with the measured ones. All above supplies data and evidence for practical application or the revision of the lightweight concrete code.
