摘要
通过对预应力装配式异形柱节点和现浇节点的低周反复加载对比试验,从滞回性能、耗能、承载力、刚度、变形等多方面进行分析,了解其受力与抗震性能。试验表明,预应力装配式异形柱节点完全能满足承载力和刚度要求,耗能理想,且节点破坏小,延性和变形恢复能力更佳。
Through the test of precast post-tensioned specially shaped column-beam subassemblages and e- quivalent monolithic connection, the loading and seismic behavior were studied , including characteristics of hysteresis curves, energy dissipation, strength, stiffness,displacement and so on. Experimental results indicated that precast post-tensioned specially shaped column-beam connections could easily meet strength and stiffness demand,and had excellent energy dissipation ability. Unlike the monolithic specimen, the precast specimen didn＇t experience severe joint distress, and had better displacement ductility and re-center ability.
