摘要：

在改进的带步长限制的序列线性规划(sequential linear programming，SLP)优化思路基础上，编制优化程序，并将其应用到型钢混凝土和钢筋混凝土梁的优化中.实例表明，该优化方法收敛快速且准确.通过对型钢混凝土和钢筋混凝土优化结果的比较可知，钢筋混凝土梁在无梁高限制时较型钢混凝土梁经济.

Abstract:

Based on the improved move limit method of the theory of sequential linear programming (SLP), this paper develop a program applied to optimization of steel reinforced concrete composite and reinforced concrete beams. Practical examples indicate that the optimization method converges quickly and accurately. Besides, reinforced concrete beam is more economical than steel reinforced concrete composite beam without constraint on the height of beam section according to the comparison of their optimized results.

Key words: sequential linear programming (SLP); steel reinforced concrete composite beam; reinforced concrete beam; optimization; quadratic interpolation
