2、gMechanicsName:XXXXXXXXXXXXXXXXXXDirectedby:XXXXXXXXXXXXXXXXXXV摘要近年来地震灾害频繁发生,其引发的惨痛后果让人们陆续开始关注建筑结构的抗震问题,节点破坏成为框架倒塌的土要原因之一。最近人们发现了一种能用于抗震加固的新型材料AFRP(芳纶纤维布),其较高的抗拉强度和易于弯折施工等优点使其拥有良好的前景。本文综合运用ANSYS以及ABAQUS对AFRP布加固梁柱节点力学性能进行有限元分析。运用拟静力法模拟了在地震荷载作用下的AFRP加固梁
3、柱节点的力学分析,并与未作加固处理的梁柱节点的力学性能进行比较分析。本文共设置了12组钢筋混凝土梁柱节点的加固试件,将有限元分析得到的承载力、水平位移、刚度系数等数据对比。结果表明AFRP加固梁柱节点能够增加梁柱结构的承载力和刚度,改善梁柱节点的抗震性能。关键词:AFRP;节点;加固;抗震;有限元VIABSTRACTInrecentyears,earthquakesoccurfrequently.Itresultedindevastatingconsequencesmadepeoplestarti
