Tendon

Definition

A tendon is a steel strand used for prestressing a concrete member.

Purpose

Tendons are used to apply a compressive force to concrete, improving its performance and allowing it to handle greater loads. This prestressing process enhances the tensile strength of the concrete, making it more durable and resistant to cracking.

Examples of Use

1. Bridges: Tendons are used in the construction of prestressed concrete bridges to enhance their load-carrying capacity and longevity.
2. Buildings: In high-rise buildings, tendons help reinforce concrete beams and floors, providing additional strength and stability.
3. Parking Structures: Prestressed concrete, using tendons, is common in parking garages, where it helps support the weight of vehicles and prevents structural degradation.

Related Terms

• Prestressed Concrete: Concrete in which internal stresses are introduced to counteract tensile stresses, achieved through the use of tendons.
• Rebar (Reinforcing Bar): Steel bars used to reinforce concrete, enhancing its tensile strength.
• Post-Tensioning: A method of prestressing concrete where tendons are tensioned after the concrete has been cast.

Notes

• Installation: Proper tensioning and placement of tendons are crucial to ensure the desired prestressing effect and structural integrity.
• Materials: Tendons are typically made from high-strength steel to withstand the significant forces applied during prestressing.
