Thanks for the continued input.
Based on the 2003 IBC, the reference welding code is AWS D1.1-2000. I guess I assumed this was implied based on the applicable building code.
All welding appears to be fillet welds.
Trust me, I am very concerned. Wish they would have called prior to actually...
I appreciate the quick responses.
Prior to posting on this site I had asked the fabricator for any and all information pertaining to the steel that has been installed. He indicated he would be providing me with said info. I am suspect at this point, but will come back if I get information...
Let me begin by pleading ignorance when it comes to Mechanical Steel Tubing.
I have client who has installed a three-story spiral staircase in a residence. They have used Mechanical Steel Tubing for the column. It appears to be a 3" pipe, but the client is uncertain how the steel was produced...
My question is whether anyone can give me some history on the use of fly ash in structural concrete. As an office standard, we do not allow the use of fly ash according to our specifications. I have never really been given a satisfactory answer as to why that is the case. I was wondering if...
I now see the error of my ways. Indeed AISC and AISI are actually the same just presented in a different manner.
As an engineer that has just been introduced to this board and am posting for the first time, I would like to say thanks for everyone's responses and thanks for this board.
The thickness is 14 GA.
According to AISC 9th Edition Table 3 (Page 1-92) all A500 Grade B steel is cold formed. Initially this is why I thought that I would need to design according to AISI. But in AISC it provides load tables for structural tubing with A500 Grade B. So which should govern...
I am determining the allowable bending stress for a 1 1/2x1 1/2 tube using ASTM A500 Grade B steel. This is referenced in both AISC 9th Edition and AISI Cold Formed Steel Design Manual. For AISC the bending equation is typical, but for AISI there is an omega value to devide your allowable by...
