本文介绍一种检验多层单跨刚架弹性稳定性的简单方法。粮据N.J.Hoff提出的用力矩分配收敛准则确定刚架的压屈荷载并利用无剪力分配法和集体分配法的概念,给出了检验多层单跨刚架的弹性稳定性的简单算式。
This article describes a simple method to check the elastic stability of multi-span single-span rigid frames. Based on the convergence criteria of torque distribution proposed by N.J.Hoff and the concept of no-shear distribution and collective distribution method, the simple calculation formula for checking the elastic stability of multi-span single-span rigid frames is given.
