INTERFACE SLIPS IN STEEL REINFORCED CONCRETE BEAMS UNDER ELEMENTARY LOADS
Based on the experimental materials, bond-slip behavior of the steel reinforced concrete (SRC) beams is analyzed. By use of theory of elasticity, differential equations of interface slips in the steel reinforced concrete (SRC) beams are presented by dividing the cross section of a SRC member into three elastic integrants by flanges of steel. By analyzing the characteristic of the loads, the slip displacements formulation between steel and concrete of a SRC simple beam subjected to pure bending, symmetrical concentrated load and uniform pressure respectively can be derived. The slip displacements along beam longitude direction in three cases are shown as slip curves. It is shown that the theoretical results are reasonable and fit the experimental results very well. The results can be used to describe the interface slips between steel and concrete under complicated loads, and to study the bond and slip constitutive relationship of the interface slips between steel and concrete.
