摘要

摘要: 结构可靠性分析是衡量工程结构不确定性的重要手段，其中一阶可靠度方法（FORM）因简单高效而被广泛使用，但依赖于梯度信息，且对高维非线性问题可能陷入不收敛.该文引入自适应改进白鲸优化算法（hybrid Alibababeluga whale optimization,HABWO)进行工程结构可靠性分析，其中白鲸优化算法(beluga whale optimization,BWO)更新策略控制算法开发阶段，结合阿里巴巴与四十大盗优化算法(Alibaba and the forty thieves algorithm, AFT)的智慧等级与更新机制控制算法探索阶段，并发展了自适应策略来平衡算法的探索和开发能力.HABWO结合一阶可靠度方法寻优可靠指标，具有较好的全局寻优和收敛能力.最后，通过三个工程结构可靠度分析案例进行验证，比较了6种不同的群智能优化算法.分析结果表明，所提方法比其他智能优化算法具有更高的计算精度和稳定性.

Abstract: Structural reliability analysis is an important technique in the uncertainty quantification of engineering 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-dimensional 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 capacity, and the intelligence level of Alibaba and the forty thieves algorithm was combined with the updating mechanism to control the exploration capacity. Moreover, the adaptive strategy was developed to balance the exploration and exploitation, and the adaptive enhanced BWO was combined with the FORM to find the global reliability 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.
