Study on Residential Building of Constant Area and Different Shape Using ETABS

Abstract

Earthquake is a form of disaster which occurs due to Natural or Man-made errors resulting in extreme damages to human civilization and any form of structure created by us. Recent example of such a disastrous earthquake was seen in our neighbouring country Nepal, resulting in massive destruction to the entire country destroying its economy and placing a setback of more than 10 years. It was such an unusual disaster, that it is extremely vital for survival to ensure the strength of the structures against seismic forces. In this way, there is persistent research work going on around the world, rotating around the advancement of new and better methods that can be consolidated in structures for better seismic execution. Structures designed considering exceptional methods to resist such forces and seismic forces have a considerably higher cost of development than ordinary structures, yet for prosperity against tension on the structure under seismic forces, it is fundamental. An Earthquake can be defined as vibration on the earth surface due to sudden release of energy from the Earth core resulting in formation of seismic waves. Brutal seismic forces are capable enough to destroy entire urban communities and cause tremendous loss to life and property. The seismicity alludes to the size, type and recurrence of earthquakes experienced over some stretch of time. In this study we are analysing four different cases of a tall structure G+20 considering various structure shapes considering seismic analysis as per I.S. 1893-I:2002 for zone III (betul). In this study we will determine the most suitable shape of structure in terms of forces, moment, displacement and cost of the structure.
