2404.1 Vertical glass. ¶

2404.1 Vertical glass. Glass sloped 15 degrees (0.26 rad) or less from vertical in windows, curtain and window walls, doors and other exterior applications shall be designed to resist the wind loads due to basic wind speed, V, in Section 1609 for components and cladding. Glass in glazed curtain walls, glazed storefronts and glazed partitions shall meet the seismic requirements of ASCE 7, Section 13.5.9. The load resistance of glass under uniform load shall be determined in accordance with ASTM E1300. The design of vertical glazing shall be based on Equation 24-1. Equation 24-1 0.6 F gw ≤ F ga…

2404.2 Sloped glass. ¶

2404.2 Sloped glass. Glass sloped more than 15 degrees (0.26 rad) from vertical in skylights, sunrooms, sloped roofs and other exterior applications shall be designed to resist the most critical combinations of loads determined by Equations 24-2, 24-3 and 24-4.

2404.3 Wired, patterned and sandblasted glass. ¶

2404.3 Wired, patterned and sandblasted glass. 2404.3.1 Vertical wired glass. Wired glass sloped 15 degrees (0.26 rad) or less from vertical in windows, curtain and window walls, doors and other exterior applications shall be designed to resist the wind loads in Section 1609 for components and cladding according to the following equation: Equation 24-6 0.6 F gw < 0.5 F ge where: F gw = Wind load on the glass due to basic wind speed, V, computed in accordance with Section 1609. F ge = Nonfactored load from ASTM E1300 using a thickness designation for monolithic glass that is not greater than…
