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
