i) Lateral tie in column

The main functions of lateral reinforcements in RC columns are:

  • It prevents longitudinal reinforcement bars from buckling,
  • It resists the shear force and hence contributes avoiding shear failure.
  • It confines the concrete core to provide sufficient ductility or deformability, and
  • It restrains the spliced bars and hence prevents their slip.

ii) Main steel and distribution steel in slab

  • The purpose of providing main bar is to transfer the bending load developed at the bottom of the slab to the beams.
  • Distribution bars are provided to resist the shear stress, cracks developed in the longer span.

iii) Stirrups in beams

Main purpose of using stirrups is given below-

  • It provides shear strength to column because it is found that many column fail in shear at the time of earthquake.
  • It provides confinement to concrete column and increases its compressive strength.
  • It prevents lateral buckling of main reinforcement in column.
  • At the time of concreting it prevent movement of main reinforcement.
  • It improves ductility of column. Improve dowel action of column reinforcement. In beam stirups used for lump sum same purpose as in column.
