Abstract: The load-deformation curve was investigated by experimented test on the steel high strength concrete composite beams. There is an interface slip between the steel and concrete beams during loading. The slip affect the limit load, the rigidity and the deformation. Based on the interface slip of the simply supported steel and concrete composite beams, the deformation differential equation of steel and concrete composite beams is established, the calculating formulas of the deformation are proposed for different loading cases by theoretical analysis. A good agreement is obtained between the calculating results and the experimental results.
