I thought of the nested hanger idea which is a great idea. In this case, the contractor used the web area to run plumbing waste lines along the beam length on both sides of the beam. Doh!
Ron's input is true. The installation does not comply with testing standard. I agree and Simpson agrees...
I just realized that in the process of trying to be succinct, my tone may read as a little harsh. And admittedly I a little pissed at Simpson for lack of support on this topic. My apologies.
Thank you all for contributing your opinions and sharing your experience.
Please keep them coming...
Simpson hangers can be welded and a 3/4" plate/shim may be used theoretically; however, all framing is completed already and the top flange is not accessible without major demolition. Also, it would be dangerous to weld within the proximity of the installed wood framing without major demo...
Ron,
Simpson LB210 hangers were used. The reason the 3/4" plywood was used is beacause there was a problem with matching existing floor elevation so the contractor installed the 3/4" plywood to lower the new floor elevation.
I went to the site and measured the plywood myself. It's definitely...
If Simpson requires the top nails to have shear capacity, they should also specify a minimum shear stress for the wood nailer. They do not, they simply say it needs to be a 2x.
Certainly they have to assume some minimum, there would be a reduction in capacity if I installed Hem Fir as...
The joist hangers are not used to transfer shear in this case. The top mounted hanger is in bearing and the top nailing is to provide a positive attachment to the supporting member. Once the floor sheathing is in place the shear is transferrred through the sheathing nails, this is why we have...
I asked my local Simpson Rep. He says that they can only recommend the 2x on top of the steel girder because that is the only assembly they have tested. They are won't offer help of alternatives to this situation. They are looking to a professional structural engineer (me) to determine if the...
I have a project where the contractor did not install the 2x wood on top of a W8 girder, he used 3/4" plywood on top of the steel girder. The nails in the top of the hanger were placed in the predrilled holes but on an angle (like a toenail). I know Simpson has tested their top mounted timber...
