Abstract

In this study, non-linear finite element analysis of repaired reinforced concrete columns was conducted. General repair methods for concrete with deficiency were presented. High concern was given to epoxy patching for concrete with honeycombing as this is a common problem in construction. This repair method made use of epoxy and fiber reinforced mortar. A 3D model of Metro Gaisano Alabang composed of beams and columns were determined. Using another program, reinforced concrete column was modeled as normal column, defective column, and repaired column. Non-linear finite element analysis was performed to lessen the cost required for obtaining results without compromising accuracy. Analysis of the columns show that the maximum stress is 10.55 MPa, 18.67MPa, 14.57MPa and deflection is 1.57mm, 1.87mm, 1.46, for the normal, defective, and repaired column, respectively. Comparing the results of defective column, it was found out that epoxy is an adequate material for concrete restoration.
