Numerical Modeling of Reinforced Concrete Beams

This book presents the numerical evaluation of reinforced concrete beam which is repaired with polymer modified mortar. In this study, a series of reinforced concrete beams model were built for the analysis. All those beams model were made with rectangular cross section and equipped with longitudinal reinforcement both in tension and compression region and also transversal reinforcement(stirrups)in shear span extended to the entire length of the beam with uniform spacing. The repaired beams are modeled by Finite Element Method (FEM) into half geometry due to the symmetric geometry and loading conditions. The repaired beams were modeled by 2D elements in plane-stress condition including the interface model between the parent concrete and the repaired layer. Finite Element Method used to model simple support of the repaired beams with two loading points. Furthermore, parametric study is carried out to evaluate the effectiveness and the behavior of repaired beam with different concrete properties, repairing mortar properties and also with different thickness of mortar as well.
