GFRC Beam Thickness Analysis Using FEM

Abstract

Glass fiber reinforced concrete (GFRC) beam thickness analysis has been studied in the present paper. GFRC is the widely used material in structures, over other materials to resolve the problems in concrete structures. They provide strength and stiffness to concrete beam. ANSYS has been utilized in the present work to the problem. Effect of thickness of the GFRC has been studied in the present paper by studying the deformation and strain generated. Four different sets have been modeled, all having the same outer dimensions. To change the thickness of GFRC concrete, beam dimensions have been reduced and results have been compared with the beam, which is made of concrete only. Base beam dimensions are 250×450 mm2 and length is 3000 mm. Three thicknesses of GFRC have been considered 2, 3 and 4 mm. From the results, it has been found that beam with 4 mm thickness GFRC shows less deformation compared to the other beams, which indirectly means that GFRC beam has higher strength compared to simple concrete beam. Weight comparison of all the beams has also been carried out which represents that with 4 mm thickness, GFRC is lighter in weight compared to the others.
