Which component must comply with common standards for Lintels in exterior concrete wall systems?

Lintels in exterior concrete wall systems are critical structural elements that support loads and ensure the stability and integrity of the wall assembly. For lintels to function properly, both stirrups and ties must comply with common standards.

Stirrups are vertical or bent elements used in reinforced concrete to hold the main reinforcement bars in place and provide additional support and strength. They help resist shear forces and keep the concrete from cracking.

Ties, on the other hand, are used to hold the reinforcement together and prevent buckling. They serve to maintain the position of the main reinforcements and ensure that the load is distributed evenly.

Compliance with standards for these components is essential because they collectively contribute to the overall performance and safety of the lintel system. Structural codes and design standards outline specific requirements for stirrups and ties to ensure they meet the necessary load requirements and structural integrity.

By ensuring that both stirrups and ties conform to these common standards, builders and inspectors help maintain the durability and safety of the exterior concrete wall systems.
