The main load-bearing structure of the roof is the truss system. Roof rafters must withstand not only roofing, but also wind and snow loads. As a rule, the main elements of the roof truss system are made from coniferous wood and treated with special fire and bioprotective compounds.
The loads that the truss system perceives are permanent and temporary. Live loads include: people walking on the roof, maintenance or repair equipment temporarily installed on the roof, wind and snow loads. Special loads: seismic impact on the building (in seismic areas). Permanent loads - this is the weight of the roof structure itself (roofing materials, rafters, insulation and insulation, as well as finishing the ceiling of the room).
The advantage of planed rafters is that, unlike regular edged rafters, this material is more stable, even and durable.
