Wind Load Formula:
From: | To: |
Definition: This calculator estimates the wind force acting on windows based on wind pressure and window area.
Purpose: It helps architects, engineers, and builders determine the structural requirements for windows in windy conditions.
The calculator uses the formula:
Where:
Explanation: The wind pressure is multiplied by the window area to calculate the total force exerted by wind on the window.
Details: Proper wind load estimation ensures window structural integrity, safety during storms, and compliance with building codes.
Tips: Enter the wind pressure in Pascals and window area in square meters. All values must be > 0.
Q1: How do I determine wind pressure?
A: Wind pressure can be calculated from wind speed using the formula P = 0.5 × ρ × v², where ρ is air density (1.225 kg/m³) and v is wind speed in m/s.
Q2: What's a typical wind pressure value?
A: For a 50 mph (22.35 m/s) wind, pressure is about 300 Pa. Hurricane-force winds (150 mph) can exceed 2700 Pa.
Q3: Should I include safety factors?
A: Building codes typically require multiplying the calculated load by a safety factor (often 1.5) for design purposes.
Q4: How do I measure window area?
A: Multiply width by height of the window opening in meters. For multiple windows, calculate each separately and sum the forces.
Q5: Does this account for wind direction?
A: No, this is for perpendicular wind. For angled winds, multiply by the cosine of the angle of incidence.
