Abstract

Reliability-based design optimization (RBDO) is a more rational optimization design method due to its consideration of the structure reliability requirements. A new RBDO-kriging method that combines kriging agent model and covariance matrix adaptation evolution strategy (CMAES) is proposed to solve the problems of RBDO of concrete frames efficiently. RBDO of a ten-story and two-bay concrete frame is implemented, the results obtained by comparing five working conditions show that, the refining kriging model proposed in this paper is effective, and RBDO-kriging algorithm can obtain better solution than deterministic optimization algorithm and optimization algorithm based on basic kriging model.
