摘要
给出了适用于在墙体构造柱中配置竖向钢筋并施加预应力方案、有预应力筋的墙体和普通墙体的周期反复加载对比试验 ,研究了砖墙开裂到破坏的全过程 ,分析了刚度、延性及耗能等问题 .结果表明 ,砖墙在施加预应力后 ,既能较大幅度地提高抗裂度和承载力 ,又能明显地改善变形。
By 1∶2 model contrast test of prestressed and non prestressed KP 1 brick wall with ring beams and tie columns,under alternatively horizontal low period load, the all process of cracking failing,failing mechanism,cracking resistance and strength of the sheet wall are studied,and the rigidity,ductility and energy consumption of the walls in question are emphasield.Analysis of the test results indicates:having been prestressed,the walling with ring beam and tie column not only can increase own anti cracking degree and load bearing ability to some great extent,but also improve evidently own behavior of deformation,ductility and energy consumption.
