In structural engineering, the open web steel joist (OWSJ) is a lightweight steel truss consisting, in the standard form, of parallel chords and a triangulated web system, proportioned to span between bearing points.

A basic understanding of open web steel joist framing systems, including their history, their unique features, and certain challenges associated with their evaluation and modification.

Composite Joists are open web product that are used in the construction of concrete roofs and floors allowing composite action between the joist and the concrete.

K-Series joists are light, highly efficient structural components. Their open-web configuration gives you space to conceal pipes, electrical, and plumbing, which can reduce height, adding value to your project. To learn more, including loading capacity information, please refer to …

Vulcraft's CJ-Series Joists combine the efficiency of an open-web steel joist system with the benefits of concrete slab construction. Combining these two construction materials creates a stronger system that uses fewer materials.

Strengthening of open web steel joists is often required due to the addition of rooftop units, underhung conveyors, or other loading increases not contemplated in the original specification for the joists. There are three basic methods of strengthening a joist or a joist system for additional loading: Load redistribution. Adding new joists or ...

The open-web design of steel joists and joist girders introduce a range of cost and performance advantages: reducing project weight; allowing for seamless integration of mechanical, electrical, and plumbing (MEP) systems; and making erection easier and faster.

2023年10月4日 · In structural engineering, the open web steel joist (OWSJ) is a lightweight steel truss consisting, in the standard form, of parallel chords and a triangulated web system, proportioned to span between bearing points.

Open-web steel joists possess an excellent bearing capacity with a long span superior to 15.2 m (50 ft). Since they require fewer columns, they allow for floor space optimization while minimizing warehouse organization constraints.

Open web steel joists are prefabricated steel trusses with a distinctive "open web" design, consisting of top and bottom chords connected by diagonal and vertical web members.
