Application of Grey Wolf Optimizer in Design of Castellated Beams

In this paper the recently developed method, Grey Wolf Optimizer, is employed for design of castellated beams. These types of open-web beams have found widespread use, primarily in buildings, because of great savings in materials and construction costs. Hence, the minimum cost is taken as the design objective function and the Grey Wolf Optimizer method is utilized for obtaining the solution of the design problem. A number of design examples are selected from literature to demonstrate the efficiency of the utilized algorithm. The results demonstrate that the Grey Wolf Optimizer algorithm is a potential alternative optimization algorithm to solve castellated beam problems.
