摘要
针对钢结构非规则梁柱体系弹性分岔屈曲失稳的特点,认为普通钢框架考虑梁、柱线刚度比值关系确定刚架柱计算长度的方法仍适用于非规则框架中的框架柱。运用虚功原理推导了两种典型的非规则梁的弯曲刚度,并分析了其对钢框架柱计算长度的影响。
Based onthe bifurcation buckling of abnormal beam- column steel frame, it was found that the way to ascertain column＇s effective length of normal steel frame can also be used in abnormal beam - column steel frame; the principle of virtual work was used to deduce the flexural stiffness of two kinds of Abnormal beams, and its effect on the effective length of rigid steel frame column was analyzed.
