LARGE-SCALE DOME TRUSS OPTIMIZATION WITH FREQUENCY CONSTRAINTS USING EVPS ALGORITHM

In recent years many researchers prefer to use metaheuristic algorithms to reach the optimum design of structures. In this study, an Enhanced Vibrating Particle System (EVPS) is applied to get the minimum weight of large-scale dome trusses under frequency constraints. Vibration frequencies are important parameters, which can be used to control the responses of a structure that is subjected to dynamic excitation. The truss structures were analyzed by finite element method and optimization processes were implemented by the computer program coded in MATLAB. The effectiveness and efficiency of the Enhanced Vibrating Particle System (EVPS) is investigated in three large-scale dome trusses ۶۰۰-, ۱۱۸۰-, and ۱۴۱۰-bar to obtain the weight optimization with frequency constraints.
