Optimal placement of viscous dampers in high-rise buildings using the target-oriented krill herd algorithm with a dynamic search mechanism

Lixiang Cheng, Yan‐Gang Zhao, Peipei Li, Lewei Yan et autres

Optimal placement of viscous dampers is essential for enhancing the seismic performance of high-rise buildings. In this study, we propose a target-oriented krill herd algorithm with a dynamic search mechanism (DTOKH) to optimize the placement of viscous dampers in high-rise buildings under …

Two-Step Kriging-Based Finite Element Model Updating for a Scaled Cable-Stayed Bridge under Shake Table Tests

Yi Jiang, De’en Yu, Lewei Yan

Cable-stayed bridges exhibit pronounced nonlinear response under a large earthquake. To accurately capture their seismic behavior, a two-step finite element (FE) model updating procedure is proposed to refine FE models employing a Kriging surrogate model, implemented through the uniform design approach. In …

A cooperative and competitive krill herd algorithm for structural optimization

Lixiang Cheng, Yan‐Gang Zhao, Lewei Yan

This article proposes a novel method, named the cooperative and competitive krill herd (CCKH) algorithm, in which both cooperative strategy and competitive strategy are introduced to solve the structural optimization. In the cooperative strategy, a crossover operator is established between the ‘best …
