Sizing Optimization Of Truss Structures Under Frequency Constraints With Artificial Bee Colony Algorithm

Abstract

Due the wide applications of truss structures in industries including aviation, transportation, buildings and vital structures, design and optimization of these structures have became the most active research fields. Furthermore it turns out that in many of structures that have been exposed to wind, hurricanes or violent earthquake, the optimization according weight only is not an appropriate way. So recently, many efforts have been made according natural frequencies optimization and minimization of weight. Due to the importance of optimization and control of natural frequencies in structures and to avoid resonance, calculating of natural frequencies of the truss structures in different moods based on minimization of weight have been focused. To reach this goal method have been used in this research, optimization by Artificial Bee Colony algorithm (ABC). Optimized structures are a planar 10-bar truss and a space 72-bar truss. Conclusions show these method have better quality than other algorithms and they can use engineering complex structures optimization.
