The optimum design of high-rise building structure based on the strength and stiffness of genetic algorithm

Abstract

The high-rise building structure have characteristics that multioperating mode, multivariate, multivariate, multiple constraints and multiobjective, and the characteristics of complex discrete have a great influence on structural strength and stiffness. So this paper built a comprehensive and practical objective function for optimization design of high-rise building structure. This function made the design not only meet the requirement of structure safety and good performance, but also should be make structure is reasonable and material consumption as low as possible to achieve optimal allocation of resources. On this basis, it used genetic algorithm by strict derivation to code variables, and then evolved until the objective function converged to complete the optimization design of strength and stiffness for high-rise building strength. The work put forward a method of quantitative mathematical description for structure optimization design, and has brought considerable economic benefits.
