Özet:

In this study, the isolation parameters of a structure with a seismic isolator were optimized using the cargo search algorithm (CSA). The isolation system is placed on the bottom by dealing with a sliding frame model. The purpose is to determine the isolation system that gives the lowest mountain drive without overcoming the isolator movement limits. The Matlab program is used for optimization processes and the SAP2000 program for structural analysis. The Open Application-Programming Interface (OAPI) has been used for the joint work of the two programs. Structural analyses were made using real earthquake records with close and remote field effects in the time-definition area. The linear analysis of the earthquake-isolated structure under the study resulted in the optimum isolator period and extinction rate determined by limiting the isolator movements. The analyses are made for different isolator movement limits and extinction rate intervals. Optimal results determined in the range of different shift limits and discharge rates have been achieved by achieving the upper shift limit. Because the high discharge rate causes an increase in steep drives, optimal isolation parameters are usually not in the highest discharge rate value. Therefore, it is necessary to determine the optimal isolation system parameters to obtain the lowest levels of drive. The optimum isolator parameters obtained by the used carrier search algorithm have been shown validity compared to the results of a similar study.
