FINITE ELEMENT ANALYSIS OF REINFORCED CONCRETE WIDE BEAMS USING INTERNAL STEEL PLATES AS SHEAR REINFORCEMENT

In the current study the finite element software ANSYS (version 16) was used for modeling wide reinforced concrete beams with steel plates as shear reinforcement. The results obtained by the ANSYS program were matched with the data of experiment of four wide beams having steel plates of different thickness (3 mm, 4 mm and 5 mm). The samples in this side were specified. The compression test was conducted for load-deflection curves at mid span, yield as well as ultimate load and their relation deflection, strain in longitudinal reinforcement, shear reinforcement and concrete and crack patterns. The compression results were positive. The results from the finite element analysis calculated the same outcome as that of experimental test of the beams. The loaddeflection curves resulted from the analysis of the finite element comply with the findings of the experiment in the linear ranges, but the findings of finite elements were stiffer than these obtained from the experimental findings.
