Jed, yes that is what we were thinking is that it was CFS joists and not structural steel joists. We have not been into the building yet, but were provided with "structural" drawings. I was told by someone else that the 1200 is probably a 12" CFS joist, but we were both stumped when discussing...
I did contact SJI. They have never heard of that call out ever. Actual response was "Never". It actually appears that they are CFS joists, so I guess I may go to AISI next, however, I do not believe they have as good of historical records as SJI does. Just trying to poll the elder statemen on...
Hello,
We are just getting involved in a new job where we were provided existing drawings and the floor and roof framing are denoted "As Keene Super C Steel, 1200 J14 24" o.c. and As Keen Super C Steel, 1000J15 24" o.c." respectively. Has anyone heard of Keene Super C Joists? I am fairly sure...
I like the second option, however with such a light loading I am having issues transferring the shear between the existing and new.
One option is dowels into the existing brick masonry from below. Not really what I want to do as it is only 8" thick brick masonry and you are installing dowels...
We are having a discussion in regards to providing underpinning for lightly loaded residential walls. The existing basement wall is 6'-0" tall (from brick slab on grade to underside of existing floor joists) 8" brick masonry with a two story plus attic wood framed structure above. The existing...
msquared48, that is fine I can wait. H.H. Robertson has some historic data posted on their website under the downloads area, however it does not appear to have the decking I am looking for.
I was wondering if anyone had the information on this decking? I have seen many other types of this deck posted on here, but cannot seem to find the information on this explicit variety of the Robertson decking.
You would have to verify that the concrete is not cracked in a service loading state, which could include both wind loads and your grain loading. The concrete not being cracked would allow you to use section D.5.2.9 (ACI 318-08) to get higher strengths. Also the factor will vary based on whether...
You ask two questions in this post, and here are what I am thinking for answers;
An anchor/anchor group would be influenced by an edge or a corner when the distance between the anchor and the corner/edge is less than 1.5*ca1 where ca1 is the distance from the loaded anchor with the shear force...
Bmroseetti sounds like a name I know [bigsmile]
It is the roof of a fourth floor addition of a building, which appears to have no lateral resistance in the North-South direction except for at one point in time interior 4" masonry wall butting up tight to WF column webs. It appears that after...
I was wondering if anyone has seen this roof deck system before. It appears to be gypsum poured over cardboard which spans between steel joists and wide flanges beams. At some locations the wires in the cardboard appear to be spanning over the beams/joists, however for most of the structure the...
You can manually enter the data into the areas that the program does not deem as standard bays to be analyzed. I would read design guide 11, if it is an easy floor, there is no reason you couldn't do a quick hand calculation. Hope this helps.

It appears that the joint thermal load listed is just used to determine the baseline (ambient) temperature of the structure. The program uses the start and end temperatures to determine an ambient temperature along the member. See loads - thermal loads in the RISA manual and Joint Coordinates...
