Abstract: In current century, many construction projects all over the world are going through financial crises because of high financial budgets. To economize the structure, structural optimization techniques should be used. For large projects it is necessary to go for structural optimization because it directly affects cost of construction. In this present study G+15 structures is considered and has been analysed using ETABS considering various parameters such as grade of concrete (M25, M30, M35, M40), depth of beams (300x400mm, 300x450mm, 300x500, 300x550mm), depth of slabs (150mm, 175mm, 200mm, 225mm), column size (600x700mm, 600x800mm, 600x900mm, 600x1000mm) and Flat slabs of depth (150mm, 175mm, 200mm, 225mm). The cost of the structure is calculated for each of the model. And then it is compared with the other models. The data is incorporated to MATLAB and the polynomial equation is obtained for all the models. The optimum structure elements are then chosen and the cost of the structure is optimized. Based on the study for column 600x700 mm, beam 300x550 mm, conventional slab of 150 mm, grade of concrete is M25. The cost of the structure Rs 32,22,707 which is less than all other combination. Based on the study of optimization of flat slab, column size 600 X 700 mm, beam 300 X 550 mm, slab of 150 mm and grade of concrete M35. The cost of the structure is Rs 40,97,551 and these are optimized structure combination
