Browse Forums General Discussion 1 Dec 13, 2011 11:34 am Can anyone provide info or link to minimum studs that should support either end of a 240 x45 lintel that is 2400mm wide several of my windows and doors only have a single 90x35 supporting such beams with a 90x35 accross the end in an 1800mm space i would understand that the 2 studs not including ends that would normally be there in an 600mm stud spaced frame would be pushed to the edges but in an 2400mm space there would normally be 3 studs across this area not including ends. Thanks Dean Re: Studs under an LVL 2Dec 13, 2011 1:04 pm I started out understanding your question but soon got lost in your description. By your lack of answers, apparently others have had the same problem Arfur Re: Studs under an LVL 3Dec 13, 2011 3:39 pm just to make it simple if i have a 2400mm wide opening in a frame (sliding door) and i have a 240x45 lvl above it. is 0ne 90x35 stud at each end enough to support it with another 90x35 stud sitting next to it and on the end of the lvl (full length from bottom to top plate not cut out for lvl) Re: Studs under an LVL 4Dec 13, 2011 6:35 pm You would probably have to refer to a framing guide or wait for a chippy to reply. As a layman, I haven't ever seen a beam supported this way and it doesnt sound right. If its load bearing I have seen 2 x 90x35 studs fixed together each side of the opening, checked out around the beam, as support. What value a stud would be at the end of the beam escapes me. Arfur Re: Studs under an LVL 6Dec 13, 2011 10:04 pm What is it supporting - sheet or tiled roof ? If it's a metal roof you'd maybe get away with a 50mm bearing and if tiled I'd go for two 35 x 90 nailed together giving you 70mm. It sounds a bit skinny to me and my standard building practice is usually 50mm even if the job we're doing stipulates 35mm for the common studs. What does it say on your plans or engineers notes ? Stewie Re: Studs under an LVL 7Dec 14, 2011 10:25 am Hi Dean, I've just gone through all your threads, given the amount of troubles you have, you must have a hella experience with this builder. I feel for you mate, we are in the same boat. This builder flat out refusing to admit what are clearly stated as defects according to BCA and G+T. Built: Modified H3nl3y S0h0 Q1 in Melbourne :- Never again Re: Studs under an LVL 8Dec 14, 2011 11:28 am 90mm wall, can I assume this is the bottom floor of a highest house? Really need to know what it is supporting, if it's an ext wall and has a floor joist running parallel to or on top of I'd say no problems. Or internal wall with joists sitting on it the same. Re: Studs under an LVL 9Dec 14, 2011 3:03 pm Yes emery nothing but troubles 4years on plumbers due back in feb to work out how to fix squashed sewer pipe under slab have already done 2 x relines and replace 2x sections of pipe in back yard due to incompotent back filling. Tiles grouted over with spacers installed back in feb to fix and now i need to inspect all lintels, as load bearing studs in theatre room were cut through 50% of the way under lintel. What a start to the new year i cant really blame the builder as trade persons should know how to do there job to aust standards and they have been very helpfull so far.

Unless I'm confused at what you mean, it seems to me if you have 90mm studs with a 45mm lintel crossing them naturally the stud is checked out 50% -- hence the doubling of studs each side of the opening. Arfur Re: Studs under an LVL 11Dec 15, 2011 1:19 pm The size of jamb studs are determined by - the height of the stud, the opening size, the roof load width & the type of roofing. The roof load width (RLW) for example with a trussed roof construction is the length from the ridge to the eaves. With a 'stick framed' roof the load width can vary depending upon roof prop locations. The Architect / Designer should have listed the lintel sizes together with the corresponding stud sizes for each opening. If these are not on your plans I'm sure they would supply the info.

Re: Studs under an LVL 12Dec 16, 2011 8:01 am Thanks Aus, was built though major builder as per my recent reply not very happy at the moment the subbie actullay measured a stud wrong cut though it half way for the lvl releif relized he had cut it to low then proceded to cut at correct height and use it, i was changing some doors and noticed it had started to split across the first cut he had made so now i need to check them all how this passed inspection i dont know. but thanks for reply. Re: Studs under an LVL 13Dec 17, 2011 4:51 am Well you seem to have given 3 different versions of what really happened. Arfur Re: Studs under an LVL 14Dec 19, 2011 8:55 am Sorry the post was regarding a sliding door opening, and the comment regards to cut studs in load bearing int wall Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16159 I want to build a bigger driveway (without a nature strip) than has been approved under my CDC.
