基于遗传算法的螺栓连接钢构件的优化设计

OPTIMISED DESIGN OF STEEL MEMBERS WITH BOLTED JOINTS BASED ON GENETIC ALGORITHM

简要介绍遗传算法的原理,并阐述运用遗传算法进行优化设计的流程。在保证螺栓承压、受剪承载力和钢板强度的前提下,应用遗传算法的原理进行螺栓连接钢构件的优化设计,达到降低成本的目的。算例结果表明遗传算法能成功地解决了这类构件的优化问题。

The article introduces the principle of genetic algorithm briefly,and describes the process of the optimised design employing genetic algorithm.The principle of genetic algorithm is applied to optimise the design of steel members with bolted joints for achieving the purpose of cost reduction on the premises of guaranteeing the bearing and shear capacities of the bolt as well as the strength of the steel plate.Example results show that the genetic algorithm is able to solve the optimisation problem of such components successfully.
