What is the function of purlins in relation to beams?

Explanation:
Purlins act as horizontal roof members that run along the length of the building to provide intermediate support for the roof deck and rafters, transferring loads down to the supporting beams. In relation to beams, their job is to connect to those beams and be spaced at regular intervals so the roof is evenly supported along the span. Spacing around eight feet is a common arrangement, helping the roof sheathing or deck share the load between rafters and beams efficiently. This role is distinct from carrying the roof to the walls, supporting walls, or attaching ceiling joists, which are functions of other parts of the framing.
