What is the maximum allowable area of a single section of thin exterior structural glass veneer located 15 ft above grade?

The maximum allowable area for a single section of thin exterior structural glass veneer is influenced by safety and performance standards. In this case, glass veneer positioned at 15 feet above grade must adhere to building codes that account for factors such as wind loads, potential breakage, and the type of building occupancy.

The correct choice of 10 square feet reflects a common threshold set by building regulations for glass installations at elevated heights to ensure adequate safety. This limit is established to minimize the risks associated with falling glass fragments in the event of breakage, especially considering the potential impact on pedestrians and structures below.

Higher area allowances could increase the risk of larger sections breaking during high winds or structural shifts, which is why there are stringent limitations to protect public safety. In contrast, the other choices represent areas that surpass this safety guideline, thus presenting higher risks in real-world applications.
