摘要
本文介绍变截面框架以转动刚度相等为原则，用等截面或带刚域杆件代换变截面杆件的计算方法，并通过算例指出，一般情况下，误差较小，能满足工程设计要求。可供设计人员参考。
The calculation method of frames with variable cross sections is presented in thepaper,these winds of frames are simplified into identifying cross sections or with regid—region bars by means of principle of identity--rotation stiffness of them. Caleulation exampleshave shown that the accuracy of the method is high,and engineering design demand can begenerally satisfied. It is quite useful for engineers.
