Abstract

One of the most frightening and destructive phenomena of a nature is a severe earth quake and it’s terrible after effects. Earthquake strike suddenly, violently and without warning at any time of the day or night. If an earthquake occurs in a populated area, it may cause many deaths and injuries and extensive property damage. Although there are no guarantees of safety during an earthquake, identifying potential hazards a head of time and advance planning to save lives and significantly reduce injuries and property damage. Hence it is mandatory to do the seismic analysis and design to structural against collapse. It is highly impossible to prevent an earthquake from occurring, but the damage to the buildings can be controlled through proper design and detailing. Designing a structure in such a way that reducing damage during an earthquake makes the structure quite uneconomical, as the earthquake might or might not occur in its lifetime and is a rare phenomenon. This study addresses the performance and variation of steel quantity of R.C. framed structure in seismic zones (II, IV). The present IS code 1893:2002 doesn’t provide information about the variation of steel quantity from zone to zone. This project report gives the STAAD Pro. analysis of Multistoried building with considering the earthquake effect and gives how to calculate the seismic weights and base shear for a multistoried structure manually and gives the STAAD Pro analysis and design of multistoried building in considering different seismic zones (II, IV) in India (as per IS1893 (part-1):2002) in the point of steel quantity for all design load combinations. All drawings have been prepared using AutoCAD.

Keywords: Seismic analysis, STAAD Pro, high-rise building
