摘要

摘要: 利用双向弯压作用下钢筋混凝土任意截面分析公式，用我国现行规范及CEB规范建议的混凝土受压本构关系进行正截面分析。分析结果表明，两种混凝土本构关系表述的差异对正截面极限承载力影响不大，截面分析的弯矩-曲率曲线的上升段基本重合、下降段略有差别。由两种混凝土本构关系分析的截面极限承载力与试验结果吻合均较好。

Abstract: Reinforced concrete arbitrary cross-sections are analyzed with concrete constitutive relations of China code and CEB model code.The cross-sections are analyzed under the action of biaxial bending and compression.The differences of ultimade bearing capacities analyzed with two constitutive relations are small.The ascendant segments of moment-curvature diagram are nearly overlapped.There are some differences in the descendant segments of the diagrams.The analyzed ultimate bearing capacity are corresponding well with experiment data.
