What is a Live Load in Construction?
Unpacking the Terminology. To begin our exploration, let's break down the term itself. In construction, a "live load" refers to the dynamic force exerted on a structure that is not permanent. Unlike the static forces exerted by the structure's own weight or fixed elements, live loads are transient and can vary over time.
