Final answer:
Historical rules recommended gussets that are 5 diameters wide and 7-8 diameters deep, while recent recommendations suggest 8 diameters wide and 15 diameters deep to ensure better strength and stability.
Step-by-step explanation:
Depending on the application and design guidelines, there may be variations in the recommended measurement of the gussets to be installed in the corner detail. Traditionally, it was recommended to use gussets that are 7-8 diameters deep and 5 diameters wide on both sides. More recent studies, however, advise using larger sizes; they suggest going up to 8 diameters deep and 15 diameters side-to-side. As a result, the supported structure will be stronger and more stable.
