Some joist manufacturer's are quite the prima donnas. I had one call me on several different jobs asking for the net uplift. I told him the gravity and wind load schedule is on the drawings, just take 0.6D - uplift. He told me he can't do the simple math to calculate and I need to provide it...
I would add more kickers if the reaction is too large to make the connection work.
Edit: you could also add a steel post (hss) in your wall you are rebuilding and connect to that instead of trying to make epoxy anchors work.
I would model the truss in staad or some other similar program. Make sure you apply your releases to the web members so you get accurate truss action. The columns could be modeled as pins and rollers. You could also add a support in the lateral direction for your bridging. Typically when...
Check with ASCE. They provide EO insurance through Pearl Insurance. They make you become an ASCE member to get the insurance but you get the membership for 50% off (you can get a quote first without becoming a member). I branched off on my own earlier this year and they were the cheapest I found...
Truss Joist TJIs come in a wide variety of chord widths. Is it really practical to use a TJI with a chord width less than 3 1/2" for a floor joist? Less than 3 1/2" chords sound like it will be an issue when decking and if you use the smallest TJI with 1 3/4" chord your floor deck really doesn't...
The contractor is saying 6 months+ on the trusses but the bad thing is I finished the drawings in July so he could have been half way there by now. This changing to conventional just came up last week because he wants to start the project this week. I was taught the same thing of never saying no...
@Kootk thanks for the reference, I'll check it out. I have no doubt anything is possible but what's practical and buildable is another story. The guys doing this would be guys that normally set trusses and build partition walls not some master craftsmen.
Thanks for the reply but this is the result after the architect revised the roof for conventional framing. I put in a call with them and they are going to review with the contractor and get back to me. I suggested having the ridge from the garage extend straight to the back wall then frame the...
I have a residential project where the contractor does not want to use wood trusses because of the long lead time. He is insisting I change my design from wood trusses to conventional wood frame but I just don't see how it will work with the roof geometry. I have made several attempts to try to...
Each joist manufacturer will design a 16K3(or any other size) differently. They are just required to meet the shear and moment capacities listed in the SJI manual. How they meet those requirements is up to them. The best way to analyze existing joists is to go field measure them or compare...
I would recommend removing the fill then installing some flat straps tied to the wall like they do with highway retaining walls. Also if it was not shored when backfilling it could have caused it to crack from the equipment vibration or compaction machine.
Geofoam is very expensive.
As canwesteng said use track 2 and it prints out a lot more detail in the design output. Also make sure you orientate your angles correctly. Staad automatically puts equal angles in at 45° and unequal angles at angles depending on the length of each leg. You can check the orientation with a...
Thanks everybody! I'm just going to wait to be asked to provide a receipt as most suggested. No one has asked for one yet so it seems like the norm not to provide one.
