Abstract:

基于可恢复功能结构的理念,提出新型自复位预应力预制节点(PTED节点),该节点通过预应力筋和高强摩擦螺栓将预制梁、柱和耗能角钢拼接在一起形成节点,预应力筋、梁、柱和耗能角钢可看作节点的组件。为了研究节点组件对节点受力性能的影响,进行了系列的低周往复加载试验,首先对PTED边节点进行试验,研究PTED节点整体的抗震性能,然后用新角钢更换受损的角钢,重新对其进行低周往复加载,探讨更换受损角钢后节点的抗震能力,然后分别试验研究了预应力筋和角钢对节点的受力性能的贡献。试验结果表明PTED节点是PT节点与ED节点的组合,节点在具有较好的自复位能力的同时,还具有较好的耗能能力。节点层间位移角加载到4%时,梁、柱及预应力筋基本保持弹性,可重复使用;节点损伤主要集中在角钢上,更换受损角钢后,节点的抗震能力基本等同于未受损的节点。
