NONLINEAR ANALYSIS OF REINFORCED CONCRETE DEEP BEAMS

Abstract

Investigation of fortified deep beams is a subject of an impressive enthusiasm for basic building. A deep beam is a shaft having a profundity that is similar to the traverse length. Deep beams regularly show up as move supports in elevated structures and also heap tops, establishment dividers, water tanks, canisters, folded plate rooftop structures, floor stomachs, shear dividers and sections or corbels. Never the less, most codes of practice do not give sufficient attention to the design of deep beams. This thesis provides a preview for previous studies in this field. Also, results of their previous studies are compared to estimate based on nonlinear finite element analysis using ANSYS. Many models for deep beams with different H/L ratios were made to reach a unified design approach for the deep beam. Finally, a comparison between the obtained results using the finite element analysis by (ANSYS) program and the proposed strut and tie model was made and a good agreement was obtained. The effect of shrinkage and temperature variation was studied.
