Re: STRUCTURAL STEEL: Large Pipe Column?

[Subject Prev][Subject Next][Thread Prev][Thread Next]
How about vertically slotting the largest size tube you have readily
available at the base where the moment will be the greatest. Then slip in
the void a smaller diameter tube either snug to the inside diameter or with
tabs to fill the slot and then weld together along the slotted lines.
