The importance of economic considerations in the context of structures has led many researchers to suggest new approaches for minimizing the weight of the structures. According to the situation of the world with limited time and resources, a structural engineer is responsible to represent an economic structural design within a specified time. The Structure is formed from material with different shapes that tolerate external conditions such loads and etc. Colliding Bodies Optimization (CBO) is a simple and new algorithm which is used for optimization design of structure. This method is based on a collision between two objects in one dimension. Nature always has been a major source of inspiration for engineers and natural philosophers. Meta-Heuristic algorithms is inspired from many solutions which is used by nature to solve difficult problems. The collision and accident is also a natural phenomenon which occur between objects and cars. The main idea of this algorithm is based on collision between two objects in one dimension. After collision, each colliding body moves to position with lower energy.
In this thesis, Optimal Design of Frame Structure is studied using Colliding Bodies Optimization and Enhanced Colliding Bodies Optimization. Results are compared with other research in this field by solving similar examples. In addition, some new examples are solved by this approach.
Keywords: Optimal Design, Frame Structures, Meta-Heuristics, Colliding Bodies Optimization (CBO), Enhanced Colliding Bodies Optimization (ECBO)
