１前言在工业建筑中，许多构件承受扭矩的作用，如吊车梁、框架边梁、雨蓬梁等，这些构件虽同时承受弯矩和剪力的作用，现行规范中对弯、剪、扭复合作用的构件是运用叠加法进行计算的，故而有关纯扭构件的计算方法的研究是有意义的。我国现行规范中，钢筋混凝土纯扭构件承... 1 Introduction In industrial buildings, many components are subjected to torque effects, such as crane beams, frame side beams, canopies, etc. Although these components are subjected to both bending moments and shear forces, the current specification deals with bending, shearing, and twisting. The function of the component is calculated using the superposition method, so the research on the calculation method of the pure torsion component is significant. China’s current specification, reinforced concrete pure torsion components...
