| Abstract | ||
| Horizontal Shear transfers through interfaces between two materials need to be studied accurately especially when the interface separates two different materials. In this study the two materials are concrete and bricks. This interaction can be formed in the regions where concrete is rested on brick walls in so many positions in construction. The study focuses on an experimental work through a series of push-off tests for ( concrete to bricks, cement mortar to bricks ) taking into consideration that the shear connectors are steel bars. Throughout push–off tests and due to the applied horizontal forces as slip had been attained. This forces and slips are recorded and graphically drawn. A statistical regression was made to find the most representative formula of the mechanism of shear transfer between concrete with bricks and between cement mortar with bricks. The predominant factor in shear transfer between concrete and bricks is the amount of shear connectors because as number of dowel bars increases the shear strength increases. The value of force recorded at 2mm slip for concrete to concrete was around three to four times that for concrete to bricks in existence of steel bars or steel dowels. This means that concrete to bricks is weaker than that between two concretes. | ||
