Optimal Design of Base Isolated Device by Temperature Parallel Simulated Annealing

Abstract

This paper examined efficiency of temperature parallel simulated annealing (TPSA) to obtain optimal arrangements of base-isolation devices for buildings. This technique uses simulated annealing (SA) in parallel, and is more excellent than past SA. Two buildings which were built in actual were selected to examine the optimal design. Buildings, those base-isolation devices were arranged by SA and TPSA, have better earthquake performance than that in actually designed buildings and difference in the performance of buildings designed by two methods were very small. Consequently, the search performance that TPSA is more excellent was shown.
