ANALYSING THE SEISMIC BEHAVIOUR OF SET BACK BUILDING BY USING E-TABS

Objective: To study building behavior during earthquakes always depends on its strength, durability, stiffness and adequacy of the regular configuration of the structure. Methods: The analysis always depends on the forces and importance on the cost of analyzing the structure. Creating the 3D building model for both linear and non-linear dynamic method of analyses. Understanding the seismic behavior of Setback buildings and Co-relating the seismic behavior of the Setback building with that of a building without Setback finally comparing the seismic behavior of building with a setback at every two levels to that of the building with a setback at each floor level. Study the influence of vertical irregularity in the building when subjected to earthquakes. Findings: The present study is limited to reinforced concrete framed structure designed for seismic loads (DL, LL & EL). The seismic behavior of three 8-Storied buildings with and without setbacks was studied. The buildings were analyzed using Time History Analysis and Response Spectrum Method and. Novelty: The effect of Setback is studied considering the parameters such as Time Period, storey drifts, Displacements, Storey Shears, Bending Moments and Shear Forces and correlated with the building without a setback.
