It also constitutes the kernel of the boundary integral in boundary element method. On ﬂaws if hybrid formulation is pursued. GreenÕs function provides the loading function GreenÕs function can be advantageously employed in quantitative nondestructive evaluation (QNDE)įor locating and estimating the size and extent of ﬂaws. One essential component of a monitoring strategy is to include technique forĭetecting and characterizing ﬂaws such as cracks and corrosions. International Journal of Solids and Structures 42 (2005) 4414–4435 A suitable strategy is desired to monitor their structural integrity for safety of infrastructures underĬorresponding author. Reinforced concrete (RC) beams are commonly used structural elements in Civil Engineering infrastructures. Keywords: Wave propagation GreenÕs function Reinforced concrete beam Corrosion To evaluate GreenÕs function for RC beams and can be used to detect corrosion. A simple and accurate numerical method has been presented here as a tool Negligible in all the cases considered here. The percentage error has been found to be Unit load and the output energy carried by the propagating wave modes. Technique has been evaluated in terms of the percentage error in energy balance between the input energy of the applied GreenÕs function for reinforced concrete sectionsĪﬀected by corrosion of steel unit normalized frequency has been evaluated for illustration. Of corrosion has also been included in the ﬁnite element model. Steel reinforcement has been modeled in the ﬁnite element mesh.

Which are common forms of structural elements. Threedimensional wave propagation analysis has been performed for reinforced concrete beam sections of T and L shapes Numerical procedure developed for the GreenÕsįunction has been validated using results available in the literature for an inﬁnite laminated composite plate.

Elastodynamic GreenÕs function has been derived by employing the compatibility conditions and utilizing the symmetry conditions at the loaded cross section. Received 21 July 2004 received in revised form 13 January 2005Ī semi-analytical solution procedure for three dimensional wave propagation in reinforced concrete (RC) beams hasīeen presented in this paper.
