Does ASCE7-22 Chapter 15 apply to modular concrete gravity walls? It mentions cantilever walls and shows a mortared brick wall in the C15 section. It looks more like it is addresses fences and simple barriers. Each block in our wall is 2.5'x2.5'x5' and are 4,000lbs each with no mortar just...
An interior roof equipment screen wall can be designed for the forces in section 29.4.1, Rooftop Structures and Equipment for Buildings. This provision takes into account the elevation of the screen wall, which is the concern if using a freestanding wall load. This also answers the second part...
What is the proper wind load for a freestanding equipment screenwall in the field of a roof (ie outside edge zones 2 or 3)? Parapet pressure does not seem pertinent as the wall is a substantial distance from the edge of the structure. The freestanding wall load methodology seems somewhat...
On behalf of colleague, Scott Hampton: This question relates to ASCE7-22 (the information related to the question below is displayed the same in ASCE7-16, except the Section, figure, and equation numbers have changed). This question relates to Table 30.10-1 (Steps to Determine C&C Wind Loads for...
