dc.description.abstract |
This study presents the numerical evaluation of reinforced concrete beam which is repaired with
polymer modified mortars. 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
mortars as well. Finally, to evaluate fatigue behavior of the repaired beams, numerical modeling is
carried out to assess the behavior of the repaired beams when subjected to cyclic loading with
applying number of cycles of loading. The numerical results showed that thick repairs which the
longitudinal reinforcement included were found to be the most effective method for repairing when
subjected both to static and fatigue loading. The result from this numerical modeling would become
valuable reference for the experimental test which will be carried out in the future. |
