不对称于弯矩作用平面的任意截面构件均属双向受弯构件。钢筋混凝土双向受弯构件广泛应用于一般工业、民用、公共建筑及桥梁结构中,如斜向搁置的檩条,受水平剎车力的吊车梁,拱壳和框架的边梁等等,但是关于它的计算方法,在我国以往的规范中没有反映,一直 Any section member that is asymmetric to the plane of action of the bending moment is a biaxial bending member. Reinforced concrete bi-directional bending members are widely used in general industrial, civil, public buildings, and bridge structures, such as swaying swaying diagonally, crane beams subject to horizontal braking force, arched hulls, and frame side beams, etc. The calculation method has not been reflected in our country’s previous specifications.
