Wind load calculations
Creating stronger, safer buildings together
To create stronger, safer buildings, architects, window manufacturers and fabricators must design for wind load from the start. Wind load is the force of wind creating pressure that glass must resist. A specific building’s wind load depends on its height, shape, relationship to surrounding buildings and terrain, as well as local wind speeds and the duration of gusts.
One key factor in calculating wind load is center deflection. Excessive center deflection can result in edge pull out, distortion of reflected images and potential contact between the glass and interior components, such as room dividers and window blinds. Wind load calculations are even more complex with insulated glass, requiring a computer-assisted wind load analysis to adequately consider the variables, including:
- Air space expansion and contraction caused by the effects of changing temperatures
- Barometric pressure, altitude and differences in weathering in the #1 and #2 surfaces; asymmetrical loading (lites of varying thickness)
- Variation in sight line or air space width
- Thermal stress
Carefully weigh these variables because they can dramatically alter the data taken from a standard wind load chart.
