Optimization of Flat Slab Using Genetic Algorithm

In this study optimization of reinforced concrete flat slab with drop and column head according to the Indian code (IS 456-2000) is presented. The optimum design of reinforced concrete flat slab could reduce its construction cost because it is usually employed in large floor area without any structural framing beams. Flat slabs are highly versatile elements widely used in construction. The objective function is the total cost of the flat slab, which consists of cost of concrete cost of steel and cost of formwork. The structure is designed by using Direct Design Method. Cost of flat slab is optimized by using Genetic Algorithm as a solver, which is an inbuilt optimization tool of MATLAB software. Trial and Error method is carried out to determine the suitable decision variables for optimization of flat slab. Results of optimum and conventional designs were compared
