Abstract

A detailed finite element model for plain concrete beams strengthened with externally bonded CFRP sheets was developed using ADINA a commercially available code and specific materials behavior models. The beams are modeled in full length in two-dimensions and all the thicknesses are included in the FEM input data. 2D-solid, plane stress eight noded quadrilaterals are used to model the concrete and CFRP warps elements, and the reinforcement bars and CFRP sheets are modeled as three node truss elements. Comparisons are made for load-deflection plots at mid span; loads at failure and crack patterns at failure. Modeling simplifications and assumptions developed during this research are presented. Conclusions from current research efforts and recommendations for further studies are included.
