G1000-2-5 非定常不規則振動応答の自乗平均値の積分値の簡易計算法 : 振幅および周波数非定常性を考慮した付加構造物系の応答(機械力学・計測制御部門一般講演(2):振動,社会変革を技術で廻す機械工学)

Seismic response of structures is nonstationary random process. Mean square value is one of the representative statistical values. Calculating method for such a response is complicated. In this paper, a simplified calculation method for integral of mean square value of the response of the secondary system is proposed using mean square value of stationary random process. Nonstationary characteristics of amplitude and frequency are considered. It is found that the proposed method gives exact values of integral of mean square value of the response.
