基于自适应改进白鲸算法的工程结构可靠性分析
Adaptive Enhanced Beluga Whale Optimization for Structural Reliability Analysis of Engineering Structures
摘要
Abstract
Structural reliability analysis is an important technique in the uncertainty quantification of engineer-ing structures,while the 1st-order reliability method(FORM)is popular due to its simplicity and efficiency.However,the FORM depends on the gradient information and may fall into local convergence for high-dimen-sional and highly nonlinear problems.The adaptive enhanced beluga whale optimization(BWO)was proposed for structural reliability analysis.The BWO with its updating rules was utilized to control the exploitation capaci-ty,and the intelligence level of Alibaba and the forty thieves algorithm was combined with the updating mecha-nism to control the exploration capacity.Moreover,the adaptive strategy was developed to balance the explora-tion and exploitation,and the adaptive enhanced BWO was combined with the FORM to find the global reliabili-ty index in structural reliability analysis.Finally,3 structural reliability problems in engineering were used to validate the HABWO-FORM,compared with 6 different metaheuristic algorithms.The results indicate that,the proposed method outperforms the comparative algorithms in terms of accuracy and robustness.关键词
