［摘要］對六片構造柱芯柱組合配筋高強度等級混凝土砌塊墻體進行低周反復試驗以研究其抗震性能，分析了不同高寬比、墻體開洞、設置水平鋼筋等對墻體破壞過程和破壞形態(tài)、承載力、滯回特征、骨架曲線、延性、等效黏滯阻尼系數(shù)、剛度及鋼筋應變的影響。試驗研究表明，在同組無洞墻體中，有水平鋼筋墻體與無水平鋼筋墻體相比，開裂荷載相近，極限荷載有所提高；相比無水平鋼筋墻體，有水平鋼筋墻體的滯回曲線更加飽滿，等效黏滯阻尼系數(shù)從開裂狀態(tài)到極限狀態(tài)逐漸提高，延性比提高了12%左右。該墻體體系具有較好的抗震性能。

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
