Open publisher page 0 citations

Abstract

On the basis of the practical structure design of engineering,the constraint conditions that the norm stipulates and the demands of various engineering standards were sufficiently considered,and a model of structural optimization with discrete variables was derived.Moreover an improved genetic algorithms(IGA) was proposed for the defects of the genetic algorithms(GA).The results by exemplification expatiated that IGA,of high accuracy,can be applied to optimal design of structures with discrete variables.
