【摘要】 通过4片带构造柱混凝土多孔砖墙片在低周反复荷载作用下的试验研究,分析了该种材料墙体的破坏特征及其强度、滞回曲线、延性等抗震性能。试验结果表明:墙片两端设置构造柱后,即能较大幅度提高极限荷载,又能改善其变形,延性等性能。另外分析了墙片的高宽比、轴向压力、构造柱等对抗剪承载力的影响,对《抗震结构设计规范》(GB5001-2001)中抗剪承载力计算公式提出补充建议,得出这类墙体的抗剪承载力计算公式。更多还原

【Abstract】 By the experimental investigation of 4 concrete perforated brick walls with constructional columns under cyclic loading,the failure,deformation,strength,ductility and force-displacement relations of the wall have been analyzed.The tested results indicate that constructional columns in the walls not only increase load-bearing capacity of the walls,but also improve their behavior of deformation and ductility.The influence of height width ratio,axial load and constructional column on the shear strength are discussed.Some recommendations for application of the formula in the Code for Seismic Design of Building(GB5001-2001) are presented.Based on the tested results,a formula for the shear capacity of the walls is proposed.更多还原
