【摘要】 本文提出了高层半刚性梁柱连接钢框架综合考虑材料非线性;杆件几何非线性;结构几何非线性和梁柱节点连接非线性的分析方法;并建立了能反映诸多种非线性影响因素的杆单元切线刚度矩阵。利用文中的非线性分析模型编制了电算程序,该程序能求解高层多跨半刚性连接钢框架的极限承载力。更多还原

【Abstract】 This paper presents analysis investigations in the effectof material nonlinearity,geometrical nonlinearity of both members andframes and nonlinearity of beam to column joints upon behaviour of flexi-bly-jointed highrise buildings.The member tangent stiffness matrix whichacounts for various nonlinear influence factors mentioned above is establi-shed.A computer program which can perform whole range studies of semi-rigidly connected frames up to the ultimate load carrying capacity is alsoimplemented.更多还原
