Stirrup

Definition

A stirrup is a vertical loop of steel bar used to reinforce a concrete beam against diagonal tension forces.

Purpose

The purpose of a stirrup is to enhance the structural integrity of concrete beams by providing additional support against diagonal tension forces, preventing shear failure.

Examples of Use

• In reinforced concrete beams, stirrups are placed at regular intervals along the length of the beam.
• Structural designs for bridges often incorporate stirrups to reinforce concrete beams against heavy loads.
• High-rise buildings use stirrups in their concrete beams to ensure stability and safety under various stress conditions.

Related Terms

• Reinforcement: The process of strengthening concrete with steel bars or mesh.
• Shear Force: An internal force that acts along a plane parallel to the direction of the applied load.
• Beam: A horizontal structural element that supports vertical loads.

Notes

Stirrups are essential for maintaining the structural integrity of concrete beams, especially in areas subjected to significant shear forces, ensuring long-term durability and safety.
