基于离散变量的张弦桁架截面优化设计
Sizing Optimization Design of Truss String Structure Based on Discrete Variable
采用Matlab语言编程，建立一个张弦桁架结构模型，对该计算模型在各荷载工况下的受力性能等进行分析，得出最不利荷载工况组合；同时编写了基于离散变量的张弦桁架优化设计程序，采用基于离散变量的一维搜索优化算法对拟定的张弦桁架计算模型进行优化，并与相关文献的优化结果进行对比分析，优化分析结果表明基于离散变量的一维搜索优化算法进行的截面优化，得到的解显然是最优解，采用本文方法优化后的结构重量仅为原来结构重量的75.1%，而且优化结果可以直接应用于结构实际设计中。
russ string structure model was writed in the language of Matlab, and performance of truss string structure were analyzed all load conditions, disadvantage combined load condition was acquired. Based on discrete variable, optimum program of truss string structure was writed, and a computation model was optimized by using this method. By comparing to related documents, results indicate that the best solution not only can be receive by using this method, optimum structure weight is only 75.1% of original structure weight, but also the result can be applied to design.
