If the WF is not straight when installed, what impact will it have on the building structure?

Wide Flange (WF) is one of the main steel profiles widely used in building structures, especially high-rise buildings, warehouses, and wide-span construction. The precise installation of Wide Flange (WF) is crucial, as even the slightest misalignment can significantly impact the overall strength and stability of the building.

So, what are the impacts if Wide Flange (WF) is not installed straight? Here's a complete explanation.

The Importance of Straight Flange (WF) Installation in Structures
WFs are designed to optimally withstand compressive and tensile loads when positioned precisely. A straight position ensures that overhead loads are evenly distributed to the foundation without creating unplanned additional forces.

Impact of Wide Flange Installation
1. Uneven Load Distribution
A tilted or misaligned WF causes the load to:

• Concentrate at a specific point
• Not optimally transferred to the foundation
• This increases the risk of long-term structural failure.

2. Additional Forces (Eccentricity)
Misalignment of Wide Flange (WF) creates bending and torsional forces that were not accounted for in the initial design.

Impact:

• Structures deform more quickly
• Steel works beyond its design capacity

3. Risk of Cracks in Concrete Elements
In combined steel and concrete structures, misaligned WFs can cause:

• Cracks in concrete beams and columns
• Damage to the joints between steel and concrete

4. Difficulty Installing Other Elements
Misaligned WFs will complicate the installation of:

• Connecting beams
• Floor slabs
• Roof and wall frames
• As a result, the work will be imprecise and take longer.

5. Reduces Building Lifespan
Structures that do not work according to design will:

• Experience material fatigue more quickly
• Require more frequent maintenance and repairs
• Causes of Wedge-Free Frames (WF) During Installation

Some common causes include:

• Initial measurement errors
• Uneven foundation or base plate
• Imprecise welding and bolting
• WF already curved before installation

How to Prevent Wedge-Free Frames During Installation
To optimize Wedge-Free Frame installation:

• Perform accurate measurements and leveling
• Ensure the base plate and foundation are completely level
• Use tools such as a water level and theodolite
• Check the condition of the Wedge-Free Frame before installation

Use experienced workers

Conclusion
Wedge-free frame structures (WF) during installation can have various serious impacts, ranging from uneven load distribution to reduced building lifespan. Therefore, careful installation of Wedge-Free Frames (WF) is a key factor in maintaining the safety and strength of the building structure.
