钢筋混凝土Z形截面柱框架节点抗震性能试验研究
Experimental research on seismic behavior of Z-shaped column joints in RC frame
摘要
Abstract
To study the seismic performance of Z-shaped section column joints in RC frame,cyclic loading tests were carried out on eight 1/2-scale interior joints with Z-shaped columns.Failure modes,hysteretic carves and skeleton curves of the joints were obtained,and the main parameters for estimating the earthquake resistant behavior of the joints were also studied,such as shearing capacity and ductility of the joints.The values of the load-bearing capacities of specimens were compared with those calculated from formula present in existing specification.The results show that the shearing capacity of Z-shaped section column joint may be perdicted using the formula of the two L-shaped column joints.The analytical results are in good agreement with experiments.The experiment parameters affecting the seismic behavior of the joints,including the axial compression ratio,the amount of the joint stirrup,shear compression ratio and ratio of pier length to pier thickness were analyzed.It is shown that the ratio of shear compression is the most important factor for the ductility.The smaller shear compression ratio of joints have good displacement ductility and hysteretic behavior.The pier length to pier thickness ratio has a little effect on the ductility.关键词
