首发时间:2006-09-05
摘要:本文通过对低周期反复荷载下3个粘钢加固框架中节点进行试验,分析了其破坏模式与受力性能,明确该类节点的滞回曲线特征,得到其延性系数和等效粘滞阻尼比系数,并建立了该类节点的抗剪承载力计算公式。

Analysis on seismic behavior of RC frame exterior joints strengthened by bonding steel reinforced sheets
Abstract:Based on the tests of three full-scale beam-column joints under cyclic load The mechanical behavior such as failure state hysteretic behavior, displacement ductile coefficient and equivalent hysteretic damping coefficient of the exterior joints are discussed. Calculating formula of shear bearing capacity of the joints is established.
Keywords: bonding steel reinforced;frame exterior joints finite element analysis ductility and energy consumption shear capacity
