@jayrod12 @Craig_H @SinStrucEng Thanks for the suggestions guys. The contractor complained about blowouts when I tried to detail it with foam removed and with the concrete formed to the face of the ledger. This is a 2 story building at floor level for what it's worth. I'll give the ICF-VL...

Hey Guys, Does anyone have any experience detailing ledgers on ICF walls? It seems kind of difficult considering the 2.5" foam layer. Either the anchors are cantilevered or I have to have a 6x ledger to be flush against the ICF core and still under the sheathing. Hoping someone has a good...

Hey Guys, When doing a HSS to HSS knee connection(with no plate), what welds do you typically use? Also, for an HSS sitting on an HSS does a fillet weld work? I've attached a sketch for both. Thank you!

@jayrod12 thanks for the response and that's interesting. Are you saying they cut the end of the log to fit into a beam hangar or similar?

Hey Guys, Does anyone know where I can find good info on the design of wood log beams and trusses and also connections? For the trusses, I'm thinking lag screws are the only real option but I'd rather avoid lag screws for conditions where I have a joist at 24" o.c. across a log. If anyone has...

Hey Guys, When you do concrete wall opening reinforcement, do you extend it all the way to the ends of the wall? Or do you just extend enough past the opening to develop it into where it needs to go? For example if I have openings with a "beam" of horizontal reinforcement below, can I just...

@driftlimiter thanks for the response could you explain "trim" bars? I haven't heard this term. I assume those are the diagonals at corners? And ao you gwnerally consider those enough to transfer the load so those segments aren't overloaded?

Hey Guys, So I have a concrete shearwall with a significant amount of openings in it. I'm wondering if I can treat it like a perforated shearwall where I only consider the full height segments for shear but get the full length for OT. Would I need special detailing for this(like diagonals at...

Hey Guys, I'm working on an ICF structure with wood floor/roof framing. I've been trying to find details for the framing to the wall at the floor level but haven't had much luck. Do you guys know a resource that has some of these details? Or do you have details you've used before? For the...

Hey Guys, Basically what's in the title but, when you're evaluating shearwalls for OT. Do you consider the height of the shearwall the moment arm or the distance from bottom of wall to top of diaphragm the moment arm? Especially in truss diaphragms where the wall can start 2' below the top of...

Hey Guys, Just wondering if you actually check your wood diaphragm for gravity loads(outside of special cases with extreme loads) and how you do it? I've looked around and it seems like everything assumes lateral controls the design. Is span rating just always controlled by lateral? Thank you!

@STpipe @phameng thank you, that makes sense I'll give it a shot just need to remember the fundamentals like you mentioned.

I have walls as shown below on all 4 sides @phameng I'm just trying to decide how to account for the diaphragm sections hanging over the walls

Hey guys, I'm working on a building that has roof overhangs on all 4 sides over a porch. How do you typically approach this from a diaphragm design standpoint? Do you treat it as a 3-sided diaphragm? I've attached an image of the general layout.

@driftlimiter Here's an image that shows it in plan view. Don't I need blocking parallel to the shearwall to develop the load into the diaphragm? Or is that only if the diaphragm allowable shear can't handle it in the shearwall length?

@driftlimiter Thank you that makes sense. The only thing I'm not understanding is the drag component. Don't you need blocking to act as a drag component into a diaphragm in the perpendicular direction of the trusses? Or is that typically only required in the parallel direction

@phameng Gotcha, and I've attached an image with a few markups added. Not sure if that helps but basically trying to understand how to attach a perpendicular truss into a shearwall and transfer the load into blocking to develop it into the diaphragm

Hey Guys, I have a couple of questions regarding drag in wood buildings(and in general). 1. When using blocking in the diaphragm for drag/development into the diaphragm, all of the blocks need to be connected with a strap right? Or can you just use the diaphragm nailing into them? 2. I have a...

Hey Guys, I'm designing a truss as a drag member in my diaphragm. It's connected along a shearwall to the top chord of the truss w/a34's. It runs into a wall that separates it from another truss aligned with it on the other side. I was going to add a Simpson cs16 to transfer the drag load but...

@phamENG thank you that makes sense
