I cannot find a definition of "Concentrated Force" in AISC. Does anyone know is AISC has defined a bearing length limit for a force to be considered concentrated. I wonder specifically with regard to web buckling. Checks for web local yielding, local crippling, and sidesway buckling all account...
ajh1 - I noticed that about the bolt specification last night. I am going to contact the pipe designer and point that out, and make sure I'm checking for the correct spec. on the bolt strength.
Bolts are in tension only, I want them pre-tensioned for proof loading and to keep things tight...
Yep, 2.5" diameter A325 bolts, pre-tensioned. I'm designing a bolt-on padeye to connect to a 9 foot diameter steel pipe flange (for a water intake). The bolt size/strength is over-sized, but the holes in the flange are 2.688" and they'll have them available for bolting up the pipes in final...
AISC has published Entering and Tightening Clearances for bolts up to 1.5" dia.(Table 7-16 in the 13th edition Steel Manual). Does anyone know about clearances for larger bolts? In my case I have 2.5" A325 bolts. I need to keep things as tight as possible to minimize plate thicknesses. Any...
So I can't seem to get the joint results to show up in my reports. It doesn't work for either the default file of the custom one I have. Title shows up in the report, but not the tables. The table are in the model and it has saved results. the xml code for the report is:

I am getting the following incorrect message in SAP steel design output.
Warning: kl/r > 300 (AISC B7)
This is a tension member the actually has kl/r = 143
Has anyone else had this problem, and if so do you know if there is a fix for this bug.
I'm trying to work out the demo of the existing bridge built in 1963-64. I have the shop drawings for most of the structural steel. Some of the steel is ASTM A7, no problem. There is also a lot of what they call BSS 968. I'm guessing this is BS 968 an old British steel spec. The design documents...
