框架结构变更定理与结构的极限分析

The Theorem of Structure Variation of Frame Structure and Limit Anolysis of Structure

本文利用框架结构连续变更定理对框架结构进行结构极限分析,用数值计算与递推公式相结合的方法避免了结构重分析中总刚度阵反复组装,编制了电算程序,算例结果是令人满意的.

By the use of theorem of structure continual variation of framestru- eture a limit analysis of frame structure is cavvied out.By using the method of numerical calculus combined with recurrence formula,repeated assembly of global stiffness is avoided.The calculation program of electronic computer is formulated. The results of calculation examples are satisfactory.
