摘要：
This study proposes an efficient technique called displacement method of analysis and applies three metaheuristic algorithms, namely Colliding Bodies Optimization (CBO), Enhanced Colliding Bodies Optimization (ECBO), and Vibrating Particles System (VPS), to perform the simultaneous analysis and optimal design of trusses. The proposed method was applied to the minimum weight design of some planar and spatial truss structures. To investigate the accuracy and effectiveness of the presented method, the problems were designed using the same metaheuristic algorithms through pure force and pure displacement methods as analysis tools (non-simultaneous). Then, the resulting structural weights were compared. © 2020 Sharif University of Technology. All rights reserved.
