［摘要］对六片构造柱芯柱组合配筋高强度等级混凝土砌块墙体进行低周反复试验以研究其抗震性能，分析了不同高宽比、墙体开洞、设置水平钢筋等对墙体破坏过程和破坏形态、承载力、滞回特征、骨架曲线、延性、等效黏滞阻尼系数、刚度及钢筋应变的影响。试验研究表明，在同组无洞墙体中，有水平钢筋墙体与无水平钢筋墙体相比，开裂荷载相近，极限荷载有所提高；相比无水平钢筋墙体，有水平钢筋墙体的滞回曲线更加饱满，等效黏滞阻尼系数从开裂状态到极限状态逐渐提高，延性比提高了12%左右。该墙体体系具有较好的抗震性能。

Abstract: Low cyclic loading experiments were carried out on six constructional column-core columns combined reinforcement high-strength concrete block wall to study its seismic performance. The influences of different height-width ratios, opening hole in walls and  setting horizontal rebar were studied on the failure process and failure pattern of the wall, bearing capacity, hysteresis characteristic, skeleton curve, ductility, the equivalent viscous damping coefficient, stiffness and rebar strain. Test results show that cracking load of reinforced wall with horizontal rebar is the same as that of the reinforced wall without horizontal rebar in the same group wall without opening hole, but the ultimate load increases. Comparing with the wall without horizontal rebar, the walls with horizontal rebar have a more full hysteresis curve, the equivalent viscous damping coefficient gradually increases from cracking state to ultimate state，and ductility ratio increases by 12%, which indicates that the wall system has well seismic performance.

Keywords: constructional column; core column; reinforcement high-strength concrete block wall; hysteresis curve; ductility; height-width ratio
