Now a day the eager for construction of Multi-storey structures are growing rapidly. The main moto behind the
growth competition in the present world and also to make for more economical and spacious in all directions. Theoretical
calculations for Multi-storey structures are very crucial and hence the demand for rapid and quick softwares is growing
faster. This study Report basically utilises the system programs like Staad.ProV8i and ETABS16 for Multi-storey building
design and analysis of 2 forms. The standard codal provision of Indian code is used. The structure considered of the two
forms are RCC and Composite structure with G+20 storey. In this two cases of Multi-storey buildings we are performing the
design and analyze and comparison among the structures. STAAD. Pro V8i & ETABS 16 both are utilised for the concrete
design, time history analysis, response spectrum analysis and p-delta analysis. The weight of Composite structure is 94.45%
that of RCC structure
