摘要
在分析框架结构破坏机理及抗震加固策略的基础上,针对复合材料(FRP)加固法的特点,提出了基于框架节点区域和框架柱的FRP抗震加固混凝土框架整体抗震性能的方法,并分别对基于框架节点和框架柱的FRP加固方式和相关试验研究进展进行了分析。结果表明:对梁柱端部及节点核心区域进行合理的FRP加固,可以有效提高框架节点和框架结构整体的抗震性能;对框架柱进行FRP约束加固,能显著改善框架柱的延性,实现合理的破坏机制,从而提高框架结构的抗震性能。
The failure mechanism of RC frame and strategy of seismic reinforcement are analyzed.For the charac-teristics of FRP reinforcement,the method of seismic strengthening the RC frame with FRP is presented based on strengthening beam-column joints and frame columns.Then,the methods of seismic strengthening the frame joints and column with FRP and experimental research progress are studied respectively.The analysis results showed that the seismic behavior of frame joints and RC frame can be notably enhanced by s...
