Wind Load Equation:
| From: | To: |
The wind load equation (WL = q × G × C) calculates the wind pressure on structures according to Philippine building codes. It considers velocity pressure, gust factor, and pressure coefficient to determine design wind loads for structural safety.
The calculator uses the wind load equation:
Where:
Explanation: The equation calculates the wind pressure on structures by considering the basic wind pressure, gust effects, and shape characteristics of the structure.
Details: Accurate wind load calculation is essential for structural design in the Philippines, ensuring buildings can withstand typhoon forces common in the region and meeting national building code requirements.
Tips: Enter velocity pressure in kPa, gust factor, and pressure coefficient. All values must be valid positive numbers. Refer to the Philippine Structural Code for appropriate values.
Q1: What is velocity pressure (q)?
A: Velocity pressure is the dynamic pressure component of wind, calculated based on wind speed, air density, and exposure category.
Q2: How is gust factor (G) determined?
A: Gust factor accounts for wind turbulence and depends on structure height, terrain category, and dynamic response characteristics.
Q3: What affects pressure coefficient (C)?
A: Pressure coefficient depends on building shape, orientation to wind, roof slope, and specific surface being considered (windward, leeward, side).
Q4: Are there different wind zones in the Philippines?
A: Yes, the Philippines has different wind zones with varying basic wind speeds. The National Structural Code of the Philippines provides zoning maps.
Q5: When should professional engineering consultation be sought?
A: For all structural designs, complex buildings, or when uncertain about input parameters, consult a licensed structural engineer familiar with Philippine codes.
