Economical span to depth ratio is around 10. The slope is 1/5. Spacing of trusses should be in the region of 1/4 to 1/5 of span. Fan trusses are used when the Rafter members of the roof trusses have to be subdivided into ODD number of panels. Pitch =L/h=4 to 10. h=L/4 to L/10 . The mass per sq.m of : Fink trusses is lowest for spans from 15m ...
