摘要
从大、小偏心受压构件截面的界限破坏条件出发,着重考虑中和轴角变化的影响。采用简化的平行线法计算中和轴的位置,用有限元法对钢筋混凝土十字形截面柱界限轴压比进行分析。对钢筋混凝土十字形截面异形柱轴压比限值提出了设计建议。
On the basis of the limit failure conditions of the section of eccentric compression member ,this paper uses a parallel-method to calculate the position of neutral axis when the angle of neutral axis changes and uses finite element method to study the ultimate axial compression ratio for cross-shaped R.C. columns. Then useful advices for design and construct is given .
