摘要
本文考虑结构的材料非线性、几何非线性、节点区锚固钢筋的滑移和节点刚域等因素的影响,采用中点刚度增量法,编制了钢筋混凝土框架全过程分析程序。该程序具有较强的功能及通用性,可以模拟试验,对各类多层多跨框架进行全过程分析;且计算与试验结果吻合较好,从而为研究钢筋混凝土框架的非线性设计方法提供了理论分析手段。
In this paper, a general program of full range nonlinear analysis for reinforced concrete frames in consideration of the influence of the nonlinearity of materials and geometry, the slip of anchor bars in the joint areas, and the rigid region of joint is drawn up by using the method of semi-ineremental rigidity. The program has very high efficiency and very common usability. It can be used to simulate the frame experiments and to conduct full range analysis for various types of frames. The computed results are in good agreement with the tested results. So the program provides an efficient means of theoretic analysis in studing nonlinear design method for reinforced concrete frames.
