Item STRENGTHENING AND REPAIR METHODS IN IRAQ FOR REINFORCED CONCRETE BEAMS(2015-01-30) MOHAMMED, Anas Malik; TUNÇ, GökhanShear or flexural failure, or both, may occur on reinforced concrete beams due to blast loading. In this study, the methodology explaining how to repair the damaged structural elements using locally available materials in Iraq is presented with analytical design calculations and finite element methods. Fiber reinforced polymer (FRP) composite materials are commonly used across Iraq for rehabilitation and repair of damaged structural elements. The applications of these available materials along with their strengthening methodologies are investigated specifically for damaged RC beams under explosive loadings. In particular, the attention is given to FRPs since they provide effective solutions for repair and rehabilitation of blast damaged beams. In this study, a total of nine beams with and without FRPs are used to understand the impact of damage and how effective the strengthening methods are based on ACI-318-2011 and ACI-440-2R. These beams are also modeled using ANSYS software. The results from analytical equations and the FE models indicate that the FRP reduces the total deflection while it increases the capacity of beams in shear and flexure. In order to verify the ANSYS results, a simple Visual Basic program was also developed to calculate the actual beam capacity in shear and flexure using the equation in ACI-318-2011, and ACI440-2R-2008. The results from the visual basic program were compared to the results from ANSYS.
