Optimization Of The Base Isolators Application Using Genetic Algorithm

Document Type : Research Article



Quake isolation is a comparatively new method for designing earthquake-resisting buildings. Instead of increasing the resistance of the structure against lateral pressures, this method is based on reducing the pressures on it. Economic expenses comparing with other methods are against widespread application of this technology. Therefore, this paper; aiming at the economic aspects of this method, considering the present approach of the codes, focusing on this method’s applicatory and practical aspects, making changes in prevailing processes of designing structures, and using optimization technology of genetic algorithm; presents a program in Fortran environment. This program is, in fact, a combination of the programs of isolation designing and that of genetic algorithm optimization, and its main goal is to reduce the expenses of isolating structures, considering the applicatory and practical aspects of this technology. Based on the dimensions of a certain site, this program is able to examine the various plans of columniation while considering the matters related to superstructure and implementation and finally suggest a plan which leads to the production of an isolation system with lower expenses.
