过去,钢筋混凝土结构采用现浇,构件截面尺寸较大,整体刚性较好,扭矩作用相对于轴力、剪力或弯矩而言,它属于次要地位,其配筋可根据经验在构造上加以考虑即可。但随着构件向薄壁、高强及装配化的方向发展,荷载及跨度的不断增大,抗扭计算就显得愈来愈重要了。近年来,国外对受扭构件强度及变形计算机理、抗扭计算全过程分析、复合扭问题、截面混凝土应力限制及配筋构造问题,都引起普遍重视。本文拟对国外抗扭计算研 In the past, reinforced concrete structures were cast in-situ. The cross-sectional dimensions of the components were large and the overall rigidity was good. The torque effect was a secondary position relative to the axial force, shear force, or bending moment, and its reinforcement could be based on experience. Take it into consideration. However, with the development of components in the direction of thin-walled, high-strength, and assembly, and the continuous increase of loads and spans, the torsion calculation becomes more and more important. In recent years, foreign countries have paid great attention to the issue of the strength and deformation of torsion members, the analysis of the whole process of torsional calculation, the compound torsion problem, the stress limitation of the concrete in the section, and the problem of reinforcing structure. This paper is intended to study foreign anti-torsional computing
