本文主要研究钢筋混凝土构件在弯矩和扭矩共同作用下的强度计算．扼要阐述了国内外关于钢筋混凝土弯扭构件强度理论研究的发展概况，并对组合受扭构件的破坏机理进行了分析．根据极限平衡的思想，吸取了桁架理论的模式特征，提出了《考虑相关影响的迭加计算方法》，并用实验方法加以验证．由于随机因素的影响，理想方程用于实际，还需根据试验结果对基本方程进行必要的修正． 论文附有计算实例，用对比的方法，分析了所建立的强度计算方法具有节省材料的经济效益．并借以说明计算方法具有实用简便的优点．
This paper mainly studies the strength calculation of reinforced concrete members under the combined action of bending moment and torque. In this paper, the development of theoretical research on the strength of the flexural-torsional members of reinforced concrete at home and abroad is described, and the failure mechanism of the composite torsion members is analyzed. Based on the idea of limit equilibrium, the model features of truss theory were drawn, and a “superposition method for considering related effects” was proposed and verified by experimental methods. Due to the influence of random factors, the ideal equation is used in practice, and the basic equations must be modified as necessary according to the test results. The paper is accompanied with calculation examples. Using the comparison method, the strength calculation method has been analyzed to save the material economic benefits. And to illustrate the calculation method has the advantages of practical and simple.
