Steel Frame Construction: Advantages and Considerations

Advantages

1. Reduced Construction Time: Can reduce build time by up to 50% compared to traditional methods.
2. Lightweight: Reduces overall load on the structure, beneficial in seismic zones.
3. Durability: Less prone to issues like cracking and moisture-related problems.
4. Thermal Efficiency: When properly insulated, can offer better thermal performance than traditional construction.
5. Precision: Factory-made components ensure high accuracy and consistency.
6. Flexibility: Allows for easier future modifications and additions.

Considerations and Potential Drawbacks

1. Specialized Expertise Required:

   • Needs contractors with specific experience in steel frame construction.
   • May be challenging to find in areas where the method is less common.

2. Design Limitations:

   • Best suited for uniform weight distribution.
   • Complex designs or cantilevered sections may require costly reinforcements.
   • Typically limited to 4 stories or less.

3. Moisture Sensitivity:

   • OSB sheathing and gypsum board are susceptible to moisture damage.
   • Proper waterproofing and vapor barriers are crucial.

4. Interior Finishing Limitations:

   • Drywall used for interiors may limit hanging heavy items without special anchors.
   • Requires planning for mounting AC units, heavy shelves, etc.

5. Thermal Bridging:

   • Steel conducts heat, creating potential thermal bridges every 40cm.
   • Can be mitigated with proper insulation techniques (e.g., exterior EPS panels).

6. Cultural Perceptions:

   • In some regions, may be perceived as less durable than traditional construction.
   • Can affect resale value in markets that prefer conventional building methods.

7. Acoustic Considerations:

   • May require additional soundproofing measures compared to masonry construction.

Best Practices for Typhoon-Prone Areas

1. Robust Connections:

   • Use hurricane straps and strong connections between roof, walls, and foundation.
   • Ensure proper anchoring to the foundation.

2. Aerodynamic Design:

   • Implement hip roofs or low-slope roofs to reduce wind uplift.
   • Minimize roof overhangs.

3. Water Management:

   • Use high-quality, properly installed moisture barriers.
   • Implement effective drainage systems around the foundation.

4. Wind-Resistant Cladding:

   • Choose and properly install cladding materials rated for high wind speeds.

5. Reinforced Openings:

   • Use impact-resistant windows and doors or install storm shutters.

6. Regular Inspections:

   • Conduct routine checks, especially before and after typhoon seasons.
