Yes, that makes sense. Thank you HD

Hi Everyone, I am designing a trapezoidal shape house and I wanna know how to get the reaction on the inclined shear wall. If I assume earthquake hits from either x or y direction then it's easy to find the reaction on that shear wall using the angle. But what if the earthquake direction is in...

Hello everyone, Where can I find good shear wall schedule and notes? I searched online and couldn't find anything useful Thank you

I will use H2.5 clips both sides. I think that will work

Hello everyone, I am designing a deck with knee braces. It's designed as a separate structure so there is a gap between the existing house and the deck. Because of this gap knee brace has to be connected to the blocking between deck joists, not to a beam. Please see my sketch to visualize this...

Thank you everyone for your help. One more question. If they drill a hole in the beam for the threaded rod, it weakens the beam, right? It's gonna be in the tension zone. The truss bottom chord is 2x4 so let's say they use MST straps it's wider than 2x4 members. My solution is to sister the...

what if they put straps for tension on each cut?

Hi everyone, I have a remodeling project and it's under construction now. The builders cut the existing truss bottom chord to place a 21' span beam where the wall used to be. The inspector wants approval for this. The beam was designed for ceiling loads since the architectural plans didn't...

Hi everyone, My client is adding a deck to an existing 2 story house ( See the sketch attached). The city requires that we check existing house for additional load per IEBC section 1103.2. My plan is to do a seismic analysis of the existing building alone and then with the deck. After that we...

Very helpful, thank you

Hi everyone, I have a deck addition project and it's gonna be attached to an existing 2 story house. The plan checker is asking to check existing house for additional seismic load from deck. It says, "please justify (E) lateral force resisting system of house subject to additional lateral load...

alt0, do you mean SDPWS?

Hi everyone, For shear walls that are short I know that we have to reduce capacity by 2b/h for seismic design. But, what if wind governs? I couldn't find any requirement for reduction for this case. Can you please help me find references? Thank you

Very clear. Thank you

ok got it. One more question. For collector diagram we use shear wall load and diaphragm load (plf). I use story shear for my shear wall line loads but you're saying I should use Fx level force for shear wall load? Thanks

I agree, Fx is lower then design Fpx but the story shear is higher than Fpx at the 2nd level. It's a 2 story house. Fx is the level force but I'm talking about story shear

My Fpx design value is lower than story shear. Should I scale the story shear down to Fpx design value? Thanks

Hi, I have a question about collector design. I use ENERCALC to generate seismic base shear and force distribution, story shears. But ENERCALC has 2 level and story forces: Fx and Fpx. Should I use Fpx, diaphragm force to design collector elements? I think if I use it the collector diagram...

also, some thicknesses are not found in the IBC table for some reason. That's something I wanna understand too. Thank you so much for your great answers!

So if it's 24/0 it means it's only for the roof? or is it for one story maybe? Thanks
