4032 衝突のある構造物の初通過破確率の推定法(G10-6 衝突・接触問題,G10 機械力学・計測制御)  [in Japanese] 4032 Estimation Method for First Excursion Probability of Structure with Collision  [in Japanese]

Collision characteristic is observed at joints of the structures. A practical estimation method of the first excursion probability of such structures subjected to random excitations such as seismic motions is proposed. First, the first excursion probability of structures with collision is obtained from theoretical method. Next, when the tolerance level is normalized by the expected value of the maximum response of the structure without and with collision, the first excursion probability can be estimated independent of natural period and clearance, respectively.
