Comparative Study of Multistoried (G+3) Residential Building using ETABS Software and Manual Calculation

Abstract

The main purpose of using software’s for design and analysis of multistoried building is to save time and to start the construction work with in the earliest time with accuracy. ETABS software is widely used today for design and analysis of multistoried building for its more accurate performance compared to other software’s performance. In the ancient times the designers used manual calculation process to design a building. It took a lot of time to make analysis and design of a structure as well as a lot of money for the designers for their hard effort. Today’s practice is to provide a design as quickly as possible. In that respect accuracy is also an important criterion that should also be within the permissible limit. This paper discusses the analysis of a four storied building (G+3) and how much we can rely on this software (ETABS) for using building analysis and design. It is found that ETABS always shows slightly higher value for all types of load, moment and shear calculation compared to manual calculations. This is why ETABS is safe to use for the analysis purpose of multistoried building.
