摘要
根据六片双肢短肢剪力墙结构试件低周反复荷载试验,量测了试件在荷载作用下的变形和钢筋的应变。根据截面内钢筋应变值采用直线和曲线两种方法拟合了截面内的应变变化情况。据此计算出各试件墙肢截面内钢筋和混凝土的应力和截面内力大小,以及各试件墙肢内的局部弯矩和整体弯矩大小。分析了内力的变化规律,并对不同肢厚比大小的短肢墙结构进行了定量评价。
According to the experimental research on the short-limb shear wall subjected to cyclic loading, the effect of flange width/thickness ratio and ratio of stiffness on the energy dissipation and ductility have been analyzed. Finally, some suggestions for engineering design are also presented in this paper.
