摘    要:在简要分析了汶川地震中钢筋混凝土框架结构的震害后,通过芳纶布(AFRP)加固钢筋混凝土框架节点的抗震性能试验,研究了不同加固方式对混凝土梁柱节点抗震性能的影响。研究结果表明:采用AFRP加固后的梁柱节点,极限承载力和抗震性能得到了显著改善,破坏形式由脆性破坏变为延性破坏。

关 键 词:汶川地震  节点  加固  抗震性能

Abstract:Based on the field surveys in seismic regions after the Wenchuan Earthquake,damage features of beam-column joints are summarized and analyzed.Three steel reinforced concrete beam-column joints strengthened with AFRP sheets and one un-strengthened joints are tested for comparing their seismic performances.Based on the experimental results the effect of different rehabilitation schemes area is analyzed.It is found that the ultimate strength and seismic behavior of the joints strengthened with AFRP are improve...
Keywords:Wenchuan earthquake  Beam-column joints  Rehabilitation  Seismic behavior
