Shear Strengthening of RC Beams with FRP Composites: Database of FE Simulations and Analysis of Studied Parameters

The use of externally bonded fiber-reinforced polymer (EB-FRP) composites for shear strengthening reinforced concrete (RC) beams presents many challenges given the complex phenomena that come into play. Premature bond failure, behavior interface layer between FRP and substrate, brittle nature cracks, adverse interaction internal steel stirrups EB-FRP are some these phenomena. Compared to experimental investigations, finite element (FE) technique provides an accurate, cost-effective, less time-consuming tool, enabling practicing engineers perform efficient, accurate nonlinear dynamic analysis as well parametric studies on RC strengthened with EB-FRP. Since 1996, numerical have been carried out response using FRP. However, only a few related in composites. In addition, analytical models reported so far failed address encompass all factors affecting contribution resistance because they mostly based limited scopes. aim this paper is build extensive database (FEA) evaluate their strengths weaknesses through various studied parameters.
