摘　　要：本文阐述了遗传算法的特点和实现方法,并通过对遗传算法的改进,建立了桁架结构的优化模型,其中采用实数编码避免了二进制编码所带来的缺陷。另外,增加了一个角度设计变量,分两种情况利用遗传算法对十三杆桁架作了进一步优化,算例表明了该法的可行性和有效性。This paper represented the characteristics of GA （ Genetic Algorithms ） and the method how to realize it, the optimum design model of truss structure was established with the improving GA , the disadvantage brought about by binary encoding was avoided by using real encoding. In addition, an angle variance was added, the further optimum was made to the thirteen bar truss structure by dealing with two iustanee for taking GA , the example indicated the feasibility and reliability of GA.
