The economy of a multistory building depends on the spacing of columns which in turn depends on panel size of slab. The objective of this work is to design an economical G+5 building by finding the optimum spacing of columns. This work is limited to plot area of 30 m X 30 m (with Aspect ratio of Panel varied from 1 to 4) for first case and in second case they were 30 m x 30 m, 30 m X 24 m, 30 m X 18 m and 30 m X 12 m (with Aspect ratio of sites varied from 1, 0.8, 0.6 and 0.4 respectively). In case two each plot area is again divided into panels of different aspect ratios. Here, Aspect ratio is ratio of longer dimension to shorter dimension of panel. The structure is modeled, analysed and designed as per IS : 456 – 2000 using Staad.Pro. Failed members are re-designed till all members are safe. This procedure is repeated for all cases and the quantities of steel and concrete are noted. It was observed that for 30 m x 30 m plot area for aspect ratio = 1, in Case 1- Case 41 with 25 columns and in Case 2- Case 31 with 12 columns were observed to be the most economical. In these two cases, Case-1 is more economical. In Case 1, Square module 30 m X 30 m with spacing of columns at 5 m and 25 panels in both sides was found to be cost effective. In Case-2 rectangular module 30 m X 24 m for aspect ratio 0.8 with spacing of columns 15 m X 12 m and 4 panels in both sides was found to be cost effective. For rectangular module 30 m X 18 m for aspect ratio 0.6 with spacing of columns 15 m X 6 m and 6 panels in both sides was found to be cost effective. For rectangular module 30 m X 12 m for aspect ratio 0.4 with spacing of columns 15 m X 6 m and 4 panels in both sides was found to be cost effective.
