Eaves Beam - Section Properties Load tables and charts - The interaction between vertical and horizontal loading is shown to allow the most efficient selection when using wind loading to BS6399 part 2. The values shown are ultimate values in kN and are based on the Eaves Beam being connected to the first purlin by the eaves strut(s) which restrains the eaves beam and transmits part of the horizontal wind loads through the diaphragm action of the roof. Restraint struts are required on all spans see page 51 Design criteria are valid when the eaves beams are fitted exactly as shown in the...
