Finite Element Analysis of Concrete Beams with Carbon Fibers and Fiberglass

Abstract

AbstractIn structural analysis, most problems are complex and accurate solutions are obtained for their governing equations only and for limited types of structures of load characteristics and simple engineering. Thus, numerical procedures such as FEM are used to obtain approximate solutions for realistic types of problems. The computer program ANSYS is a sturdy and interesting engineering finite element package that may be utilized to solve a lot of problems. FEM has become a most commonly method used to study the stress, deformation, and other engineering parameters. FEM uses complicated mathematical equations to accurately approximate how the complex structure reacts to a certain load or condition. FE bundles like ANSYS solve thousands or millions of these equations to find a solution for a model. Handling all these equations as a whole be difficult and mostly impossible to solve manually. ANSYS is an inclusive general-purpose FE computer program that contains different elements implemented in the program. This article describes the application of nonlinear finite element models to the analysis of rectangular concrete beams. In this work, the material parameters that must taking into consideration to investigate the CFRP beams behavior that are young modulus (Ec), compressive strength fʹc, and the tensile strength (ft). Also, young modulus (Es) and the yielding strength (fy) of steel are considered. Furthermore, the geometry factors considered are the beam width, effective depth, longitudinal reinforcement area and shear reinforcement area.KeywordsBeamConcreteBendingStrengthReinforcementGlass
