NIAZIT Composite System

NIAZIT Composite System is a modern, engineered structural floor system designed as an advanced solution for composite slabs in both steel and concrete structures. In this system, traditional secondary steel beams are replaced by NIAZIT steel joists combined with temporary formwork, resulting in improved structural performance, reduced material consumption, and easier execution.

Introduction to NIAZIT Composite System

In the NIAZIT Composite System, shear connectors—typically in the form of angles or channels—are welded to the top chord of the NIAZIT steel joist. Since steel joists are used instead of conventional steel beams, the system can be safely applied to both steel and reinforced concrete frames without structural limitations.

Unlike the NIAZIT Deck System, which utilizes permanent galvanized steel decking, the NIAZIT Composite System employs temporary formwork, enabling a more economical and faster construction process.

Main Components of the NIAZIT Composite System

1. Top Chord
The top chord of the NIAZIT joist is formed by a T-section and:

• Acts as the primary compression member of the joist

2. Web Members
The web consists of vertical and diagonal members made of plain or deformed reinforcing bars:

• Vertical members → compression elements

• Diagonal members → tension elements

• Welded to both top and bottom chords

• Responsible for transferring shear and axial forces

3. Bottom Chord
The bottom chord is composed of:

• Steel flat bar (PL), or

• ST37 steel plate
  and functions as the main tension member of the joist.

4. Reinforcement Elements (Shear Connectors)
Reinforcement components are considered strengthened sections of the joist and:

• Are designed based on critical structural conditions

• Increase shear and flexural capacity

• Are applied where required by structural calculations

5. Assembly Rebar
Assembly rebar is a non-load-bearing element that:

• Is used in concrete frames to facilitate joist placement during concreting

• Is not required in steel frames due to nominal welding of the bottom chord to the main beam

6. Shear Studs
In NIAZIT joists:

• Shear studs are typically T-shaped angle connectors

• Welded to the top chord

• Ensure full composite action between the concrete slab and the steel joist

General Configuration of the NIAZIT Composite System

• NIAZIT composite joist used in steel structures (Figure 1)

• NIAZIT composite joist used in concrete structures (Figure 2)

Key Features and Advantages

• Compatible with both steel and concrete structural frames

• Reduced steel and material consumption compared to traditional systems

• High execution speed due to temporary formwork

• Easy passage of mechanical and electrical services within the slab depth

• Flexible and fully engineered design for various project types

These advantages make the NIAZIT Composite System an ideal solution for residential, commercial, and industrial projects, improving execution efficiency while reducing overall construction costs.

Applications of the NIAZIT Composite System

• Residential and apartment buildings

• Commercial projects requiring fast construction

• Industrial buildings and warehouses

Key Differences Between NIAZIT Composite System and Conventional Composite Floors

Conclusion:
The NIAZIT Composite System is more suitable for large-scale and complex projects due to reduced material usage, faster construction, and optimized costs, while conventional composite floors are generally used in shorter spans with standard execution requirements.
