摘　　要：本文用国内外试验资料进一步论证了“构件变形后平截面保持为平面”的计算假定。按照这个假定,提供了任意配筋矩形截面双向受弯构件强度的具体计算公式。还提出了对称配筋矩形截面双向受弯构件强度的简化计算方法。On the basis of available domestic and foreign tests, this paper further proves the principle that the entire transverse section of a member, originally plane, remains plane and normal to its longitudinal fibers after deformation. According to this principle, the strength calculation formulae for rectangular section reinforced concrete beams with arbitrary reinforcement subject to biaxial bending and its simplified method for rectangular section with symmetrical reinforcement are presented.
