Seismic Analysis of Regular and Irregular Building by using Time History Method

The intention of this project is to evaluate (or) estimate the seismic analysis vulnerability and response of regular and irregular shaped multi-storey buildings context of India. Linear time history analysis has been performed to learn about the influence of shape of a building on its response to various loading. 10(ten) storied regular shaped (rectangular, and L-shape) and irregular shaped (Plan Irregularities, Vertical Irregularities, stiffness irregularity) buildings have been modeled using software ETABS 2016 for Hyderabad (seismic zone 2), India. Effect of dead load and live load on different shaped structure with Time history method has been meticulously analyzed considering the different shapes of building which has same mass. Comparative study on the maximum displacement of storey and centre of mass of different shaped buildings due to static loading has been explored. The base shear, displacement, response spectral acceleration and the earthquake displacement is analyzed in time history method. It is concluded that there is increase in bases shear, story displacement and story drift in irregular building than in regular building due to earthquake forces in the seismic zone ii using ETABS Software 2016.
