LH Joist

Definition

A type of long-span high-strength bar joist.

Purpose

LH joists are used in building construction to support floors and roofs with long spans. They provide strength and stability, allowing for open spaces without the need for numerous supporting columns.

Examples of Use

• Commercial buildings: Supporting the roof structure in warehouses, shopping centers, and other large buildings.
• Industrial facilities: Providing long-span support for floors and roofs in factories and plants.
• Gymnasiums: Ensuring open, unobstructed interior spaces in sports facilities.

Related Terms

• Joist: A horizontal structural member used to support a floor or ceiling.
• Beam: A large, horizontal structural element that supports joists and other loads.
• Truss: A framework of beams or bars that supports a roof or bridge.

Notes

• Proper installation and alignment of LH joists are crucial for maintaining structural integrity and safety.
• These joists must be designed and specified by a structural engineer to meet the specific load requirements of the building.
• Regular inspection and maintenance can help detect any issues with joists, ensuring the continued safety and performance of the structure.
