Question: 1 / 400

True or False: Purlins can be smaller than the supported rafters.

True

False

The assertion that purlins can be smaller than the supported rafters is actually false. Purlins are horizontal structural members used to support the roof and act as a framework for attaching roofing material. They are typically positioned on top of the rafters and serve to distribute loads evenly across the rafters.

Since purlins are designed to bear the weight of the roofing material and any additional loads, their size is determined by the span they need to cover as well as the type of roofing material used. If purlins were smaller than the rafters they support, it could lead to inadequate support and structural failure under load. Therefore, purlins must generally be of sufficient size or strength to ensure that they can efficiently support and transfer the loads to the rafters without compromising the integrity of the structure.
