Investigation of Inelastic Structural Performance of G+10 Building Structure Under Seismic Load condition

Abstract

The inelastic capacity of structural systems is a crucial determinant of their performance and durability during seismic occurrences. Comprehending and precisely forecasting inelastic behaviour guarantees greater structural safety, less damage, and improved post-earthquake operability. This research examines the inelastic capacity and seismic resilience of several structural systems, concentrating on steel, composite, and reinforced concrete frames exposed to varying seismic intensities characteristic of Indian earthquake zones. Analytical modelling and dynamic simulations are conducted using ETABS, using sophisticated analytical methods like response spectrum analysis, nonlinear static pushover analysis, and nonlinear direct integration time-history analysis. This analysis assesses critical structural reactions, such as plastic hinge development, narrative drift, lateral stiffness, ductility, peak strength, energy dissipation, and joint accelerations. The research adheres to national and international design standards, including IS 800:2007, IS 875 (Parts I, II, and IV), IS 1893:2016, AISC 360 (2010 & 2016), and FEMA 440, to guarantee uniformity in performance assessment In the present study the analysis of G+10 building model is carried out by using Response spectrum analysis method, time history analysis method and pushover analysis methods. The building models are analyzed with the help of ETABS Software package. The results like acceleration, time period, storey shear and base shear etc are studied as per obtained results.
