The anchorage of nonstructural components like mechanical and electrical equipment is an important element of ensuring life safety that doesn’t always get the same attention as the structural engineering required for the building itself. The key standard that governs design loads is ASCE 7. This blog post explores updated equations in the newest edition of the standard, ASCE 7-22, specifically Chapter 13, which covers seismic design of nonstructural components. We’ll walk step by step through an example of anchoring a piece of equipment to a concrete slab inside a Risk Category IV building in a high seismic area.
