Cost Optimization Of A Rectangular Singly Reinforced Concrete Beam By Generalized Reduced Gradient Method
Cost Optimization of a singly reinforced rectangular beam using the GRG method is presented in this paper. The objective function is chosen as the overall cost of the beam given by the sum of the products of unit rates of steel and concrete in rupees per unit volume (đ3) with their volumes. 28 combinations of simply supported beams of different spans subjected to different point loads and uniformly distributed loads are analyzed using EXCEL Solver. The constraints are adopted to satisfy various guidelines as per IS 456:2000 code of practice
