Types of Stirrups in Reinforcement

The purpose of stirrups is to withstand the later shear stress and diagonal tension stress in RCC structure. Therefore, the stirrups allow to resist the buckling failure in columns.

Benefits of the Stirrups in Beam and Column reinforcement:

1. The stirrups are arranged in beam and column to retain the concrete and the main rods jointly.

2. It sets the rods in the similar alignment.

3. To keep the beam and column safe from the buckling and shear failure.

4. The stirrups defy the rods under compression or tensile force.

The spacing of stirrups vary depending on the design for both column and beam. The least spacing should be 100mm and the maximum is 250mm, according to the diameter and number of the rod.

Based on the nature of construction, the following types of stirrups are mainly utilized in beam and columns :-

Single Legged Stirrup, Two-legged or Double Legged Stirrups, Four-legged Stirrups, Six-legged Stirrups.

Occasionally, three-legged stirrups are also found in construction.

Single Leg Stirrups: The single leg stirrups are used seldom since it is useful while binding only two rods.

Two-Legged Stirrups: These types of stirrups are usually and frequently used. To set up this stirrups, minimum 4 number of the rod is necessary.

Four-Legged or Multi-Legged Stirrups: These types of stirrups will be necessary for beams containing longer web widths. It is recommended to apply multiple-legged stirrup in allowed situations since they accelerate control of shear cracking, better control longitudinal splitting cracks and facilitate maintain the transmission of shear through aggregate interlock.
