What angle of glass sloped must resist wind loads from the ultimate design wind speed?

The angle of a glass slope that is designed to resist wind loads must provide sufficient resistance to ensure structural integrity and safety under high wind conditions. An angle of 15 degrees has been identified as an effective slope in this context because it balances the need for stability against wind forces while maintaining aesthetic and functional properties.

When glass is sloped at this angle, it helps to deflect wind loads more effectively than shallower angles. A steeper slope can increase the potential for stress on the glass, while a lesser angle may not adequately manage the wind pressures exerted on the surface. Therefore, a 15-degree angle is commonly used in practice because it meets both regulatory requirements and industry standards for handling wind loads in various weather conditions, making it a prudent choice for design purposes.

The other angles present either too much stress or inadequate resistance against wind loads, sacrificing structural safety or practical usability, which is why they are not considered optimal for this application.
