Types of Stirrups in Reinforcement

Generally, there is a lot of types of stirrups have been used in both column and beam reinforcement. The purpose of stirrups providing will differ for both columns and beam.

So now let us discuss the types of stirrups and provision of the spacing of stirrups in beams and column.

Mostly the stirrups are designed in a rectangular or square shape but in some of the case, it may be provided in circular or diagonally based on its purpose.

Why the Stirrups are providing in Beam and Column reinforcement?

  • The stirrups are provided in beam and column to hold together the concrete and the main rods.
  • It positioning the rods in the same alignment.
  • To secure the beam and column from the buckling and shear failure.
  • The stirrups are resisting the rods under compression or tensile force.

The spacing of stirrups will be different based on the design for both column and beam. The minimum spacing is 100mm and the maximum is 250mm, based on the diameter and number of the rod.

Types of Stirrups

The following types of stirrups are widely used in reinforcement and some special case the designer change the stirrups type based on the design requirement.

  • Single Leg Stirrup
  • Two-Legged Stirrup
  • Circular Stirrup
  • Helical Stirrup

Single Leg Stirrups

The single leg stirrups have used rarely because it mostly used when binding only two rods.

Two-Legged Stirrups

The common and widely using stirrup type id Two legged stirrups. To providing this stirrup minimum 4 number of the rod is required.

Circular Stirrup

The circular stirrup is used when the column is a round shape.

Helical Stirrups

Mostly it is using in pile column and also for the pile foundation the stirrup can use either Helical or circular.
