| Abstract | ||||
| Self-compacting concrete (SCC) represents an innovation in the building industry due to its workability. This type of concrete can flow under its own weight, fill in formwork and pass between bars without need compaction, but the mixture proportions for SCC differ essentially. The higher powder content, limited volume and nominal maximum size of aggregate, larger quantity of superplasticizers make design requirements in achieving the self-compacting concrete. The bond between SCC and reinforcing steel bars is an essential requirement for design of reinforced concrete structures. The current study investigate the effect of various parameters that affect the bond behavior between SCC and steel rebars at the maximum shear strength zone such as : concrete compressive strength, splice length ,concrete cover , the effect of confining steel and level of confinement, Evaluate the applicability of various lap splice equations, in different building codes and standards, for calculating lap splice in self-compacting concrete beams ,Finally compare between bond behavior of lap splice in conventional concrete and SCC. | ||||
