摘要
提出预应力砼截面弯矩-轴力-曲率关系的计算方法,并计算了不同预应力度下截面的弯矩-曲率关系.指出预应力度对弯曲延性的影响,同时提出增加弯曲延性的方法.
A computing method is presented for studying the bending moment, axial force and curvity relationship at the section of prestressed concrete beam. The author computates the relation between bending moment and curvity at the section under different prestressing degrees; and points out the effect of prestressing degree on bending ductility; and puts forward a method for the promotion of bending ductility.
