低周反复荷载下钢筋煤矸石混凝土剪力墙的力学性能

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，不同剪跨比的前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和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。

Mechanical properties of self-combusted gangue reinforced concrete shear walls under low-cyclic load

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.
