WF for Multi-Storey Buildings: Technical Matters to Consider

In multi-story buildings, structural elements must be able to withstand much more complex loads than in single-story buildings. One of the most frequently used steel profiles for this purpose is Wide Flange (WF). However, the use of Wide Flange (WF) in multi-story buildings cannot be simply chosen. Several important technical considerations must be considered to ensure the structure remains safe, stable, and in accordance with design calculations.

The Role of Wide Flange (WF) in Multi-story Buildings
WFs are generally used as main columns and beams that transfer loads from upper floors to the structure below. Because they carry vertical and horizontal loads, as well as earthquake and wind forces, WFs must perform optimally according to their design function.

Technical Matters to Consider
1. Selecting the Right Size of Wide Flange (WF) for the Load
Each multi-story building has different requirements for Wide Flange (WF), depending on the number of floors, span, and function of the building. Incorrectly selecting Wide Flange (WF) sizes—too small or not meeting specifications—can reduce the structure's capacity and increase the risk of deformation.

2. Material Quality and Quality Standards
The Wide Flange (WF) used must meet quality standards (SNI) with consistent steel quality. Materials with substandard quality can experience reduced strength, especially under long-term loads.

3. Direction and Orientation of WF
WF must be installed in the direction specified in the structural drawings. The position of the flange and web significantly affects the WF's ability to resist bending moments and compressive forces. Incorrect orientation can prevent the WF from performing according to the design calculations.

4. Connection Details Between WF
In multi-story buildings, connections are critical. Welded or bolted connection details must meet specifications, including size, number, and type. Inaccurate connections can become a weak point in the structure.

5. Column Alignment and Straightness
WF, as a column, must be installed perpendicular and parallel. Inaccurate alignment can cause uneven load distribution and increase unplanned lateral loads.

6. Control During the Erection Process
WF erection must be carried out under proper supervision. WFs need to be temporarily stabilized before final locking to prevent shifting that could affect the position and strength of the structure.

7. Protection Against Corrosion
Multi-story buildings have a long service life, so protecting WFs against corrosion is crucial. Proper surface inspection and coating will help maintain the long-term strength of the WF.

The Importance of Material and Installation Coordination
In multi-storey buildings, structural strength depends not only on the design but also on the quality of the materials and the accuracy of installation in the field. High-quality WF installed substandardly still risks compromising the structure's performance.

To ensure the safety and optimal performance of multi-storey buildings, ensure you use SNI-compliant WF with the appropriate dimensions and specifications for your project.
