    FAQs are kind of gone

    Hi Lex, sorry to hear that, I understand the sentiment. Lucky for us, EngTips has been updated so that every link and interface is tracked through AWS, to watch all your moves on this website and other sites, to better serve ads, isn't the future great?

    Hot Tub on Elevated Balcony

    To make your calc a little simplier, you've already identified water density at ~62.4lbs/ft^3. Just multiply by the water depth, maybe 3ft in center of tub? 62.4lbs/ft^3 * 3ft = 187.2lbs/ft^2 for the water in the tub.

    Concrete topping on CLT

    Lightweight topping is typical on light frame construction for sound performance. Typically it's dictated as <= 1.5" in thickness as that is how ASCE 7 defines the cutoff point for flexible diaphragm analysis. Not sure I understand how it would differ for your situation. Might try talking with a...

    Plywood Gusset Design

    I would strongly avoid considering glue as the primary bonding element. How many discussions have occurred on this site regarding post install epoxy anchors, even with thorough instruction from the manufacturer with details on how to install. Imagine a framer trying to build a strong and...

    Music in the Office

    Sentrifice, I nearly always work with music on, unless I'm on the phone with a client/customer. However, to emphasize, I only play music without lyrics. I tend towards jazz, lofi, video game or theme park music, etc. I believe that lyrics are distracting so I don't like listening to that, but...

    Information for Wood Log Beams and Trusses

    I know this isn't what you're looking for exactly, but here is an older US Department of Ag guide to building log framed homes (and includes a bonus section on building log furniture). Maybe there is something in here that can help you? I'm not sure what exactly you are looking for with this...

    sill plate eccentric loading

    Plate washers required within 1/2" of the sheathed edge is to limit cross grain bending in the sill plate around the washers, which will cause the plate to fail and increase drift, reduce shearwall stiffness and capacity, etc. See section 4.3.6.2 of SDPWS.

    sill plate eccentric loading

    Not sure I agree. What is the load path? we have two (sometimes three, if perforated) forces that are resolved by the shear wall. The first is overturning, which is resolved by the tension/compression elements and hold downs at end of shear wall. The second is in-plane shear. That in-plane shear...

    sill plate eccentric loading

    My concern would be where is the stud wall relative to the foundation? Is this a concrete stemwall that can create a lip for water to collect and then move into the structure? Putting the sheathing on the outside usually provides the waterproofing we want and prevents water build up at the base...

    Music in the Office

    Do I like music while working? Absolutely. Do I like other people's choice in music while working? Almost assuredly not. I would suggest starting with the recommendations provided above, try on a pair of noise cancelling headphones, and see if that works for you. I wouldn't escalate it to...

    Decision which Packages you will use

    IRstuff, you're not wrong, I understand the sentiment, but I agree 100% with Celt83, I will generally only reference mainstream things. I will of course use System.Math or System.Drawing in C#, but I don't generally want to have to vet and trust a library stored if I am not auditing the entire...

    Decision which Packages you will use

    I don't write in Python, so I don't have anything to add to this discussion, but this is one of the main reasons that I do not like python, anytime I look at python code it seems I just see a whole bunch of library references with very little actual work performed by the programmer, makes...

    Resource for design of washer plate connections to wood

    Years ago I made this flow chart to try and understand the requirements for shear walls anchorage in SPDWS. The provisions in the NDS are intended to limit cross grain bending.

    Rafter hanger nail collision at ridge beam

    How do you achieve target reliability for such a loading condition like cross grain tension when codified design values are not provided? I would not suggest nor endorse a loading scenario that induces tension perp personally, but I suppose I cannot prevent you from doing so.

    Double 3-Sided Roof Diaphragm

    I'll be honest and say I have not dug that deep into steep roof design, but I think a member on these forums (pham or Kootk maybe?) likes to include the attachment here whenever this question comes up, discussing folding plates. I've never taken the time to read through the attachment, but I've...

    Double 3-Sided Roof Diaphragm

    35ft is the allowable L' length in SDPWS, and the allowable aspect ratio is 1.5, check section 4.2.5.2. I've shared photos like this on this forum below, but here is a real quick sketch-up showing where blocking would be required. Keep in mind this is for seismic design, not wind, so your...

    Double 3-Sided Roof Diaphragm

    To address the question in the OP regarding the offset shear walls inducing lateral load at end of 3-sided diaphragm: you can fairly easily model this conceptually and account for it in your design, biggest issues will be drift at the unsupported side of the cantilever, determination of location...

    Simpson Strong Wall as a True Portal Frame?

    XR250, OP hasn't indicated, but I'm guessing they have slenderness issues, or the wall system is taller than what portal frame provisions allow.

    Simpson Strong Wall as a True Portal Frame?

    A picture might help here, as I am confused as well. Wood portal frames typically have a tested moment capacity that is codified where the beam frames overtop the vertical shear wall element. This is achieved by a large collection of nails into both the shear wall element and the beam element to...
