中文摘要：

为提出钢筋混凝土构件复合受力研究领域可以进一步开展的研究内容及方向,从弯剪扭复合受力分析理论、模型试验研究、强度关系曲线、规范设计方法等4个方面综述了钢筋混凝土构件复合受力分析的相关研究进展。对比讨论了国内外几种复合受力分析模型的异同,给出了现有钢筋混凝土弯剪扭强度关系曲线与部分文献的试验及有限元计算结果对比,同时指出了国内外现行规范中复合受力钢筋混凝土构件设计方法的差异。结果表明：在扭弯比较大时,理论强度关系曲线与试验值偏差较为明显;现有计算分析模型在大型复合受力箱梁裂缝控制及时变承载力分析等方面值得进一步研究及应用;应开展缩尺独柱支撑的钢筋混凝土连续箱梁复合受力模型试验研究与设计计算理论的探讨,可以借助已有的复合受力分析模型,通过适当简化,采用迭代方法进行构件的配筋设计。

英文摘要：

In order to put forward the further research points and directions, four aspects of the research progress on analysis of reinforced concrete （RC） members subjected to combined loading, including coupled bending-shear-torsion analysis theory, model experiment, bending shear-torsion interaction and specification design methods were introduced. Several models for analysis of RC members subjected to combined loading were presented, and their similarities and differences were discussed. The comparison of the existing bending-shear-torsion interaction curves, the experimental results, and the finite element results was carried out. Differences of formulas in codes or specifications for design of RC members under combined loading were compared and analyzed. The results show that the difference between the theoretic and experimental results is obvious with large ratio of torsion to bending; the existing models can be further applied and improved in analysis of crack control and time-varying bearing capacity of large-size RC box-girder structure subjected to combined loading; further experimental research and design calculation method on large-size RC continuous box girders, even with the singlecolumn support, can be conducted and an iteration method for reinforcement design of RC members under combined loading can be developed by using the existing analysis models.
