摘要
平面刚架极限优化设计是线性规划问题.采用线性对偶规划解法,解决了约束方程数目过多的问题,在静力法优化设计中,成功地处理了多余力变量的无限制变化问题.算例表明,采用线性对偶规划解法使平面刚架的极限优化设计较容易实现.
The optimum limit design of a planar rigid frame in an engineering structure is a problem of linear programming. This paper adopts the solving process of dual linear programming, solves the problem of too many constraint equations, and deals successfully with the problem of infinite change of the variables of the redundant forces in the optimum design by the static method. Examples of computation show that the result of this method is satisfactory for the optimum limit design of a planar rigid frame.
