Basic Theory Analysis On Bond-Slip Behavior Between Steel Shape And Concrete In Steel Reinforced Concrete Structures

Steel reinforced concrete (SRC) structure is a main kind of steel and concrete composite structures.SRC structural members have a relatively small sectional dimension and a high bearing capacity. SRC structures obtain a better integral stiffness, and have an excellent seismic behavior.SRC structures has been applicated extensively. The fine bond behavior between steel shape and concrete is the base of their cooperation. The cooperation is the reflection of the advantages of SRC structures. The bond behavior directly affects the bearing capacity, failure modalities, crack, deformation and calculating methods etc.Although the calculating methods in SRC codes are different in many countries, they commonly simplify or neglect the effect of bond-slip between steel shape and concrete. There are many differences and conflicts among the present research, and many problems about the bond-slip behavior are not solved at present.the bond-slip behavior between steel shape and concrete is necessary to be deeply studied and perfected.This text pays attention to release to push -out experiment,steel reinforced concrete pillar, steel reinforced concrete beam to band strength and bond-slip , constitutive relation carried on the theories analysis, to experiment the research contain important leading meaning.
