radially chamfering stiffner edges instead of a diagonal cut
radially chamfering stiffener edges instead of a diagonal cut (where you have the fillet weld on the supporting beam.) this is done for seal welding. why is this usually specified, often by oil & gas firms?
check out our whitepaper library.
i think that this stems from the standard nautical details for metal ships due to brittle fracture concerns in areas of stress concentrations. you see similar details a lot on ferries in the stiffener connections to the deck plate. there is a lot of continuous vibration on nautical vessels that is not usually a characteristic of land based structures.
we learned a lot about steel detailing from the old liberty ships...
