Stirrups are provided to hold the main reinforcement rebars [1] together in an RCC structure. Stirrups are placed at proper intervals to beams and columns to prevent them from buckling. Also, they protect RCC structures from collapsing during seismic activities (earthquakes).
Purpose Of Stirrups
- Its increase the compressive strength of column.
- It can improve the ductility of column.
- Stirrups prevent the buckling of main reinforcement in column.
- At the time of concreting it prevent movement of main reinforcement
- Improve dowel action of column reinforcement.
- In beam stirrups used for lump sum same purpose as in column.
- To provide lateral confinement to longitudinal bars
- Its provide resistance against shear and torsion
- To hold longitudinal bars during construction
- Its confine the concrete in the core ,thus improving ductility and strength
- Its prevent premature buckling of individual bars
