Why 135° Hook Use In Column Not Use 90° ?

In reinforced concrete columns, 135° hooks are mandatory for stirrups (ties), especially in seismic design, because they provide better anchorage and safety than 90° hooks.

1. Better Anchorage & Grip

A 135° hook wraps around the longitudinal bars, giving strong mechanical anchorage.
A 90° hook can straighten out under heavy compression and cyclic loading.

2. Prevents Buckling of Main Bars

Column ties hold the vertical bars in position.
135° hooks lock the ties tightly, preventing buckling of longitudinal reinforcement.

90° hooks may open under load, losing confinement.

3. Superior Confinement of Concrete

Columns need strong confinement to:

Increase compressive strength

Improve ductility

Control cracking

135° hooks maintain closed ties, ensuring uniform confinement.

4. Essential for Earthquake Resistance

During earthquakes:

Loads are repeated and reversed

Sudden energy dissipation is required

135° hooks remain intact, while 90° hooks may fail suddenly.

That’s why IS 13920, ACI 318, Eurocode all require 135° hooks in columns for seismic zones.

5.Code Requirement (Example)

IS 456 / IS 13920:
Column ties must have 135° hooks with 10d extension (minimum 75 mm).

Using 90° hooks in columns is not code-compliant in seismic areas.

So Finally 135° hooks are used in columns because they provide strong anchorage, prevent bar buckling, ensure seismic safety, and satisfy code requirements.

90° hooks are unsafe for columns and may fail under heavy or earthquake loading.
