给出了钢筋混凝土弯剪扭构件极限承载力和变形的理论表达式。它们基于空间桁架模型。考虑了平衡和协调问题，得到了斜裂缝中混凝土压杆的极限性能、剪流质心位置、剪应变在垂直剪应力和扭转应力相加的垂直面和垂直剪应力和扭转应力相减的垂直面上的分布。所提出的方程与试验结果进行了比较，并注意到良好的相关性。
Theoretical expressions for the ultimate strengths and the deformations of reinforced concrete members subjected to combined bending, shear and torsion are described. They are based on a space truss model. Equilibrium and compatibility are considered and the obtained equations involve the behaviours at ultimate of the concrete struts among diagonal cracks, the locations of centroid of shear flows and the distributions of shear strains at the vertical face where the vertical shear stresses and the torsional stresses are additive and the other vertical face where the vertical shear stress and torsional stresses are subtractive. The proposed equations are compared with test results and good correlation is noted.
