Inelastic Analysis of RC Buildings

Abstract

It's challenging to model the non-linear performance of reinforced concrete analytically. Engineers have used empirical formulas developed from various tests to create reinforced concrete structures in the past. Non-linear analysis has become an important method in structural design and evaluation of reinforced concrete elements. The method can be used to study reinforced concrete building behaviour as well as force redeployment. The non-linear response of RC structures was studied in a traditional way. It facilitates in the investigation of structure performance under a variety of loading conditions, including load-deflection and crack pattern. The reaction is governed by the structure's stiffness and ductility, as well as the structure's and constituent material's shape. The force is applied in increment, the response for every step is determined, and the capacity curve is depicted on a graph as the major parametric research in a pushover analysis. The capacity curve derived from the pushover study overlaps with the demand curves for the relevant codes. The performance point is determined by the intersection of the capacity and demand curves. For the accurate and most precise results, the most suited method is Time-history analysis. Time history method shows the actual response of the representative ground motion.
