Abstract
Bond-slip performance between section steel and concrete has influence on deformation of steel reinforced concrete beams based on results of experimental studies. Current standards on steel reinforced concrete structures do not involve bond-slip effects when calculating the deflection of steel reinforced concrete beams and this is not valid exactly. This paper describes a new method of deflection calculation for steel reinforced concrete beams, which considering the bond-slip effects on deformation. Deflection of steel reinforced concrete beams are divided into two parts: deflection of steel reinforced concrete beams under loads considering the fully bond between steel and concrete, and the additional deflection caused by the bond-slip. The sum of the two parts is the total deflection. Results show that the proposed method in this paper fits with experimental results.
