Finite Element Analysis on the Crack Width and Deflection of a Local Corroded Reinforced Concrete Beam
In this paper, the crack width and deflection of a local corroded reinforced concrete beam is investigated. The influence of the rebar corrosion on a concrete beam is analyzed first. Based on the constitutive relationship of the corroded reinforced concrete, the corroded reinforced concrete is regarded as a bond-slip composite beam which is comprised of corroded rebar and concrete. By using the large-scale finite element software ANSYS, a separate reinforced concrete beam model is developed after selecting the reasonable element. By using the proposed model, the positions of the cracks are determined. Moreover, the cracks width and the deflection of the beam at the corroded segment are calculated through using formula and extracting the results data from ANSYS. At last, the results by the standard design of concrete structures (GB50010-2010) and EN1992-1-1:2004[1] are compared through the list, which show the crack width and deflection of the local corroded reinforced concrete beams calculated by ANSYS is feasible.
