If you look at picture 3, there isn't a single truss plate connecting the two spans together untill you get to picture 2 where a plate connects the 2 spans right above the girder creating a pocket.

If my memory serves me right, I believe at that distance from the exterior wall to the left where the splice is located, we were in the hallway not in the appartment. It could be 2 spans of a girder truss.

phamENG - Thanks for the input. I think that's the way to go. Gradually moving towards the next more calculated and engineered requirement. skeletron - This is what I mean. Design requirements in NBC Article 9.23.16.2.,NBC Section 9.27. and NBC Section 9.29 simply address sheathing & gypsom...

Yea it was pretty massive about 4 ft tall. Thanks for the input, it confirms what I was thinking as well.

Basically, there's what seems to be a girder truss as you say, composed of 4 seperate trusses (see pic 4&5) and the perpendicular pitched roof trusses seem to sit on the girder truss and tie together with truss plates (pic 1,2&3). I wish I had taken better pictures, I was up there for a...

Hi, I have come accross this type of roof truss layout 2-3 times while inspecting attics in mid-sized residential light wood framed buildings. I'm wondering if anyone is familiar with this type of roof truss configuration where there seems to be a truss beam supporting 2 spans of roof...

Thanks to both of you for your replies phamENG & skeletron. phamENG - It seems the US code is clearer on what is expected when a modification is done to an existant structure compared to the Canadian Code. Like I said, I work in an area that is described as low wind and eq so the prescriptive...

Hi ladies and gentlemen, I would like to know your opinion and methodology when you get a project where the client wants to increase the size of a window or a door in the exterior walls of the homes, duplex, triplex. etc. In Canada, houses and small buildings are governed by Part 9 of the...

Yes there will be a plate with bolts restraining the bottom of the beam.

Thanks to everyone that answered, it helped clarify things alot. I think it will be simpler to have web stiffeners welded since the bevel cut will eliminate the flange at that extremity of the beam making a nailer with braces trickier to do. Not related to the post: I recognize alot of the...

Hello, I have a customer that is asking if it's possible to bevel cut a steel beam in order for them to recess a W8x31 beam into their attic. In my opinion if the cut doesn't go beyond the support width it doesn't weaken the beam in shear nor in bearing. The load on the beam isn't immense, It...
