Hi Folks,
When the engineer says my lintel is to be supported by 3 common studs each end what exactly does this mean?
I took it as having 1 jamb stud next to the lintel, 1 secondary jamb stud under the lintel member and then 2 common studs next to the jamb stud. Like this:-

Was this right or was it another config?
TIA
From my experience, I woould suggest 3 studs each end under the lintel, they are the ones that hold it up...that's how I did the lintel on the garage I just built.
Extend the lintel over another two studs. Supported by 3 common studs.Quote:

Agree - if you look at your drawing you can see that your lintel is transferring the weight of 7 studs onto two studs. You need three studs, no gap between, supporting each end of the lintel.
Thanks for clarifying that for me folks (framing plans now changed :D ). Guess what was confusing me was the fact that you can put additional studs both under and next to the lintel. As per attached I will have 3 studs under and 2 beside so all is sweet.
Bingo, and be sure to nail them all together.
On a similar topic, I installed some french doors that are 2800 wide with a lintel in an external wall 3500 wide 3200 high. I used 3 studs under each end of the Lintel. My problem now is there is a bit of give in the wall if i give a bit of a push at the top of the door Jam. I seems to be acting like a hinge about the top of the door jam.
A friend suggested running a few more studs from the floor bearer to the top plate beside the lintel supporting studs, but i dont see this as doing much because the majority of the give is directly above the middle of the doors (approx 1500 away) and the ends at of the wall dont seem to move.
Any advice would be greatly appreciated.
This is straight from AS1684 - Timber framing code : two full length studs plus one secondary jamb stud (this supports the lintel directly ie 35mm bearing length) all studs are nail laminated.Quote:
