Deep Steel Beam
Deep Steel Beam
(OP)
Hi All
I was wondering if there is a max depth for steel beams, in order to comply with AS4100 or NZS3404?
I found couple of slenderness ratios but didn't find any maximum depth limit, for welded beam in orders of 1.2-1.5m deep.

I'm aware of the 1200WB, but my question is, is there a limitation on the depth of beam in AS4100? can we design 1.5m deep or 1.8m deep beams in accordance with AS4100, or AS4100 can't be used after certain depths?
Thanks

That deep a beam needs to explicitly be checked against web and flange deformation since the sides are so deep, each quarter-section (half of the flange for example) is so far from the other half of the flange stiffener that each could bend separately under load.

A 6' deep welded/fabricated beam/plate girder is nothing exceptional. The codes and standards for the design and fabrication of these are well defined and developed. I’ve been involved in the design and fabrication of plate girders almost three times that deep at the haunch/pier bearing.
