摘要
本文通过4榀钢筋混凝土门式框架在周边荷载作用下的试验,对框架内力重分布幅度、轴力对框架极限荷载的影响,以及框架弯矩调幅后的性能进行了研究。由试验得出:不考虑轴力作用的计算会低估极限荷载达28%以上。文中还利用编制的框架非线性分析程序对试验框架进行了全过程分析,分析中考虑了节点钢筋粘结滑移、节点刚域、轴力等因素的影响。
Through the testiog of 4 reinforced Concrete portal frames under peripheral loading,the moment redistribution degree,the axial force influence on the limit loading and the behaviour of frame after adjustment of elastic moment were investigated.The results have shown that if axial force action is not considered the limit loading would be underestimated above 28% In this paper,the full—range inelastic analysis of frames has been done In whlch the influence of the bond—slip of reinforcement in joint zone,joint stiffness and axiac force action were considered
