【摘要】 对三个T形柱梁柱节点进行了反复荷载作用下受力过程和破坏特征的试验研究和分析,研究了钢筋混凝土T形柱框架结构中间节点在低周反复荷载作用下的受力性能,分析了此类节点的破坏机理和失效方式。研究表明:T形柱框架节点在反复荷载作用下,破坏特征类似于普通矩形柱节点;翼缘最后的破坏形式是轴压比引起的正截面破坏;轴压比影响节点承载力,低轴压比状态下起有利作用。更多还原

【Abstract】 Experimental research and analysis of force-bearing process and failure behavior of 3 R.C.beam-T column joints under repeated loading are achieved.The behaviors of exterior beam-T column joints under low-cycle loads is researched.The failure mechanism and the fashion of failure is also discussed.The research shows that the failure behavior of R.C.T shaped column joints is similar to R.C.beam-rectangular shaped column joints.The last failure fashion of flange is cross section failure mode which is caused by axial compression force.The carrying capacity of joints is affected by axial compression ratio.Low axial compression ratio is beneficial to the carrying capacity of joints.更多还原
