SEISMIC BEHAVIOR OF REINFORCED CONCRETE MULTI-STORY BUILDINGS WITH CONFINED CONCRETE

Abstract

The paper presents the seismic analysis method of the reinforced concrete multi-story buildings employing Mander’s nonlinear model for confined concrete behavior and bilinear model for reinforcement behavior. The action of earthquakes on the building is analyzed by using the time-history analysis method. The building structures are modeled by the finite element method based on the OpenSees software. The obtained responses of the internal forces, displacements, strain, and stress are highly consistent with the considered model suggesting that it is practically effective for the seismic-resistant design of the reinforced concrete buildings.
