多目的遺伝的アルゴリズムを用いたオイルダンパーの減衰係数とリリーフ荷重の最適選択手法

Abstract

This paper proposes an optimal method to select the damping coefficients and relief forces of oil dampers in seismic control buildings. The optimization method used is SPEA2 (Strength Pareto Evolutionary Algorithm 2) which is a multi-objective optimization method. This method was compared to the SGA (Standard Genetic Algorithm) using two plane frames for some representative design solutions. The proposed method was able to find solutions as good as or better than design solutions obtained by the SGA. Consequently, the effectiveness of the proposed method was demonstrated.
