摘要
考虑一期荷载、预应力、预制构件截面相对高度以及材料非线性、几何非线性等因素的影响，采用增量变刚度有限元法，编制了混凝土框架非线性全过程分析的通用程序。所给的单元刚度矩阵形式具有普遍性。对四榀各种类型的混凝土框架进行了模拟试验，计算结果与试验结果吻合较好。
In this paper, a general program of full- range nonlinear analysis for R. C frame in consideration of the influence of first stage load (the loading applied during the constructional stage ), pre stressing force, relative height of prefabricated components, and the nonlinearity of material andgeometry, is developed by using the method of increment rigidity. The element stiffness matrixpresented in this paper has common usability. The program simulates four frames, and the computed results are in good agreement with the test results.
