- Abstract:
- Experimental study on the fundamental behavior of box shape steel reinforced concrete(SRC)beams was conducted.Seven 1∶3 scale model SRC beams were tested to failure.The experimental results indicate that the flexural strength increases with the increase of the ratio of flexural reinforcement and the thickness of flange of the shape steel;the shear strength increases with the increase in the thickness of the web of the shape steel.Concrete filled in the box shape steel can prevent the early failure of specimens due to the buckling of the box shape steel, and increase the ultimate load.Measures should be made to strengthen the connection and co-work between the shape steel and the concrete.Formulae for flexural and shear strength of the composite beams are proposed, and the calculated results are in good agreement with the experimental results.In general, the box shape SRC beam is a kind of ductile member, and it is suitable for extensive engineering application.
