摘　　要：用M ATLAB编制了优化程序,实现带位移约束的桁架满应力优化设计方法,在迭代过程中引入松弛系数,并通过算例分析松弛系数对优化结果的影响及其原因.A MATLAB optimum design program for truss structures was developed. The full stress optimum design method for truss structures with displacement constraints is implemented in the program. The coefficient of relaxation is introduced in the iterative algorithm and the influence of the coefficient of relaxation is discussed by numerical results.
