Bottom flange of a monorail
Bottom flange of a monorail
(OP)
Hi,
When the hoist wheel loads are applied to a bottom flange of an I beam, how can I analyse the bottom flange for the local failure for bending and shear.
Thanks.

In Australia the crane code AS1418 details the procedure.

FYI: wheel loads are applied usually 0.9 to 0.95 of the bottom flange width - That is to say the loads are virtually at the tip of the flange.
But remember to check the web capacity also and the global buckling capacity. The serviceability limit should be limited to L/500 or L/600 depending on where you are. If there is a joint between beams , say at a splice, you should have a gap of no more that 3-4mm. The flange should be locally thickened near a free edge or at a splice point - This is clearly due to the point load causing larger stresses near an unsupported edge.
take care
