摘要

摘要: 在已建立的任意截面钢筋混凝土梁柱单元模型基础上，分析了单元积分时高斯点数对钢筋混凝土结构非线性分析结果的影响，分析比较了现行混凝土结构设计规范建议的用于计算弯压截面极限承载力的混凝土受压-关系和用于非线性分析的-关系的差异，并将计算结果与试验结果比较，建议合理的钢筋混凝土梁柱单元积分高斯点数。

Abstract: Based on derive beam-column element model of reinforced concrete,reinforced concrete structures are analized to take into account the effect of the number of Gauss point on the nonlinear analysis results when finite element stiffness is integrated.The difference between two concrete - relations are compared with nonlinear analysis of cross -section.The two relations are suggested by the current code for design of concrete structures,one is used for calculation of bearing capacity under bending and compression, the other is used for nonlinear analysis of concrete structures.The analytic results are compared with experimental data and suggestions on suitable Gauss integration points are given for reinforced concrete beam -colimn element.
