This paper addresses the Case study on seismic analysis of high rise building system (Ground+ 3Basements+50) storey RCC by STAAD pro v8i with application of Indian standard provisions. One of the most frightening and destructive phenomena of a nature is a severe earthquake and it terrible after effect. It is highly impossible to prevent an earth quake from occurring, but the damage to the buildings can be controlled through proper design and detailing. Hence it is mandatory to do the seismic analysis and design to structures against collapse. Designing a structure in such a way that reducing damage during an earthquake makes the structure quite uneconomical, as the earth quake might or might not occur in its life time and is a rare phenomenon. This study mainly on to understanding the results from STAAD Pro v8i software under gravity loads provision made in IS 456:2000, Results shall satisfy the general criteria from being a failure after analysis Results to improve The accuracy as per IS code 1893 : 2002.
