Abstract

Reinforced concrete beams are designed primarily for resisting the shear and flexural stresses that are exhibits on the beam sections. These two parameters are influenced by different factors.  Delay of concrete casting forms an interface between harden and fresh concretes. Interface is a surface between two sections of concrete that are not placing monolithically. This interface may affect the structural capacity of reinforced concrete members. Especially shear strength of the members at the shear plane is highly influenced by this interface. Many researches were conducted on different factors that affect the shear and flexural capacity of reinforced concrete beams varying different parameters. In this research paper, an experimental study was executed to investigate the effect of interfaces on the behavior of the shear and flexural capacity of reinforced concrete beams. Eleven beam specimens were examined through experiment. Main variables in the research were interface location (Half, one third, quarter, and one fifth) and interface configuration (vertical and inclined) for both shear and flexural beams. The test results indicate that considerable reduction in the shear capacity and relatively small reduction in flexural capacity of reinforced concrete beams due to the interfaces weakness at the joint.
