RE: OSHPD SCBF's using HSS Braces

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Going back to my elementary geometry class, a square is nothing more than a special case of a rectangle. Therefore, any code requirement for a rectangular HSS would also be a direct requirement for a square HSS. Extending this argument, any reference to a rhombus, parallelogram or trapezoidal HSS section would also be a reference for a square HSS J

Subject: OSHPD SCBF's using HSS Braces


Section 2205A. of the CBC modifies AISC 341 for SCBF's using RECTANGULAR HSS sections. The section requires them to be filled solid with cement grout. This is for OSHPD only projects.

Question: Do the really mean Rectangular and Square HSS sections or only Rectangular as stated?
