Finite Element Analysis on Impact Factors of Castellated Steel Reinforced High Strength Concrete Beams

Abstract:

In order to verify the feasibility of ABAQUS, finite element simulation analysis is used to a castellated steel reinforced high strength concrete beam (CSRHSC beam) firstly. Then we consider the strength of steel, strength grade of concrete and thickness of steel protective layer as parameters to study the mechanical properties of the beam by ABAQUS. The results show that: The bearing capacity of beam increases when the steel strength improves, but the magnitude of increase will gradually reduce with the increase of steel strength. Along with the strength grade of concrete increase, the yield strength and ultimate strength basically tend to linear increasing, the ductility tend to decreasing. With the increase of thickness of concrete cover, the ductility of the beam improves but the ultimate strength decreases.
