摘要:
为研究开洞对RC框架内填单排配筋墙体结构抗震性能的影响,设计了2个1/2缩尺两层单跨模型,一个单侧带门洞,一个对称带窗洞.通过拟静力试验,研究破坏特征、滞回性能、骨架曲线、承载力、刚度、耗能和延性等.结果表明:无洞口侧墙体沿梁、柱边缘破坏,带门洞侧门洞上部、角部墙体破坏严重;带窗洞试件窗间墙、窗洞角部墙体破坏严重;无洞口比带门洞侧的承载力高27%,无洞口比带门洞侧的初始、屈服、峰值刚度分别高7.37%、30.43%、35.97%;对称带窗洞试件的正、负向延性系数比单侧带门洞试件分别高39.55%、41.86%;单排配筋墙体是第一道抗震防线,墙体退出工作后,演变为承载力稳定的框架结构;框架实现了“强柱弱梁”、“强剪弱弯”、“强节点”的设计原则.

Abstract:
To study the influence of openings on the seismic behavior, two 1/2 scale, two story and one bay models were designed. There are doors on the one side for one model and windows symmetrically for the other. Based on the low-reversed cyclic loading test, the failure characteristics, hysteretic behavior, skeleton curves, bearing capacity, stiffness, energy dissipation and ductility were analyzed. The wall on the one side without openings was damaged along the edge of the beam and column, while the wall on the other side was damaged above the doors and on the corner. The wall between windows and the corner wall were damaged for the model with windows. The bearing capacity on the one side without openings was higher 27% than the other side with doors. The initial, yield and peak stiffness on the one side without openings were higher 7.37%, 30.43%, 35.97% respectively than the other side. The positive and negative ductility of the model with symmetry windows openings were higher 39.55 % and 41.86 % respectively than the other model. The results show that single row of steel bar shear wall is the first seismic fortification line and frame with stability load carrying capacity can function as the second seismic resistant system. For the frame, the design principle of "strong column and weak beam", "strong shear and weak bending", and "strong node" are realized.
