Effect of Stirrups Shaped on Shear Capacity of Self-Compacting Concrete Beams Provided by External Steel Plate

The stirrups are the major factor which resists the shear forces and others parameters like as aggregate and dowels are contribute with less than 7% of shear strength.Shear connectors transmit the shear forces in composite beams between steel parts and concrete, therefore these connectors can be used as vertical legs to assistance stirrups in their performance. It was also noted that the change in the Shape of the stirrups does not have a significant effect on the shear capacity, and the decrease in endurance can be compensated by reducing the distance between the stirrups, and it was also noted that the horizontal parts of the stirrups may have a limited and negligible effect, and therefore the stirrups can be replaced by I shaped instead of conventional stirrups therefore the stirrups can be replaced by I shaped instead of conventional stirrup.
