摘要
以异形柱框架结构的关键构件T形柱梁柱节点为研究对象,通过同条件的预制装配式构件和整体现浇构件的拟静力对比试验获得了预制装配式梁柱节点的抗震性能指标,结果表明预制装配式梁柱节点与同条件现浇整体节点相比,其滞回曲线、骨架曲线和平均退化曲线均基本重合;其极限荷载和极限位移的差值百分比分别为9.3%和0.4%,从而说明预制装配式节点的力学能力可以等同于现浇整体节点。
T-shaped column beam-column joints of frame structure were chosen as the research object. The seismic performance indexes of precast beam column joints are obtained by the pseudo static test of prefabricated components and the whole cast in place with same conditions. The results show that the hysteretic curves, skeleton curves and average degradation curves are basically coincident with cast joint in place with the same conditions. The difference percentages of limit load and ultimate displacement were 9.3% and 0.4% respectively. So the mechanical capacity of the prefabricated assembly joints can be equal to the cast in place.
