CALCULATION OF INTERFACE SLIPS IN DUPLEX STEEL REINFORCED CONCRETE COLUMN BY PRINCIPLE OF MINIMUM POTENTIAL ENERGY

摘要：

　　Based on the principle of minimum potential energy,the interface slips in duplex steel reinforced concrete column is calculated.According to the study of bond-slip behaviors of steel reinforced concrete and steel tube concrete,a pull-out mechanics model of duplex steel reinforced concrete column has been built.The slip displacement on the interface of steel and concrete of the column along the embedment length is derived by the principle of minimum potential energy.The calculation results show that the slip curves have the basic characteristics of quadratic curves distribute.It is meaningful to improve the design theory of SRC and study the bond-slip constitutive relationship between steel and concrete.
