モンテカルロシミュレーションを用いた構造物の信頼性評価の高速化に関する研究

抄録

Monte calro simuration is one of the effective methods to estimate the failure probability of complex structures involving many mutually dependent failure modes. However, since this method requires a large number of structural analyses, it is desirable to develop a method to improve the computational efficiency. For this purpose, new type of importance sampling method in which a concept of equivalent failure surface is introduced is proposed. Its effectiveness is demonstrated through a simple example of truss structure.
