Which truss section is relevant for calculating linear feet?

The bottom chord is relevant for calculating linear feet because it represents a continuous structural component of the truss that typically spans the distance between the supports. In a truss system, the bottom chord supports the loads that are transferred from the upper structure to the lower connections, and its length directly correlates to the project’s dimensional measurements.

When determining linear feet in construction or structural analysis, the focus is often on the lengths of members that contribute to the overall span of the truss. The bottom chord is crucial since it directly relates to the width of the building or structure.

Other sections, such as the top chord and the overhang, serve different functions and may not represent the overall span measurement needed for linear foot calculations. The top chord typically supports the roof load but might not extend the full width relevant to the framing of a space. The overhang represents a projection beyond the main portion of the truss and doesn't contribute to the primary span measured. Therefore, the bottom chord is the right choice for calculating linear feet in this context.
