Abstract:

Optimization in the field of civil engineering problems, is performed so that both technical issues are satisfied and the least construction cost is achieved. As mateiral cost constitiutes a major part of steel structures cost, its minimization is taken here the problem objective in presence of stress and displacement constraints. Jaya as a recent meta-heuristic is utilized to solve this problem. It is further enhanced with a passive congregation strategy so that shared information of the search agents helps better convergence toward global optimum. Numerical experiments is conducted on a number of benchmark structures to validate the proposed hybrid method
