混凝土框架梁柱节点FRP抗震加固研究综述
|
摘要
采用合理可行的FRP加固方式可有效改善混凝土框架梁柱节点的强度、刚度、延性和耗能能力,增强其抗震性能。本文重点从有效的纤维粘贴方式和纤维种类选择两个方面对不同框架节点的FRP加固方式进行了探讨,对比研究了平面框架节点和空间框架节点的加固方法,分析了纤维的混杂效应。对FRP加固框架节点抗震性能的试验研究进展进行了论述,并从理论分析的角度简要介绍了当前的研究现状,指出了目前所开展研究的不足和以后的研究方向。
The load carrying capacity,stiffness,ductility and cumulative energy dissipated of concrete frame joints reinforced with FRP properly can be efficiently improved,and the seismic performance is improved.In this paper,research on reinforced ways of frame joints according to fiber paste methods and types are carried out as a key point.And the recent research on the frame joints reinforced with FRP is presented.Reinforced ways of plane frame joints and space ones are compared,and then the hybrid effect of fiber is analyzed.At the same time,based on the results of the theoretical analysis and experimental research on the seismic performance of joints,the shortages of recent studies are pointed out,the research aspect of the field as well.
