I'm real confused how a structural engineer who has practiced for 40+ years is unfamiliar with load combinations? PE_JRM, what kind of projects do you typically work on?
Ah, you're right, I missed a critical step: I didn't state my assumptions. I assume there is no energy or momentum loss as we pass the core of the earth and arrive out the other side. We convert the entire gravitational potential energy from the earths radius to allow us to accelerate up the...
Waross, if we are going the magical material route, why not also just drill a hole through the earth from the other side of the sling, then we can accelerate the payload through the earth and back out the other side, reducing the unobtainium material cost and requirements?
I'm with pham on this one, this appears to be a fairly simple and straight forward framing situation, with inverted hanger and/or 45degree struts at the corners carrying the load back to the walls. Difficulty for us is understanding your drawing, it's not clear enough what is bearing and where...
On that topic, for a long time, not sure if this is still the case, but if you made quarterly US tax payments online using a credit card, the general charge from the organization collecting the quarterly tax payment was something around 1.9% of the taxes paid. So if you paid with a credit card...

Have you tried reaching out to the other engineering firm and asking how they obtained these CAD files, and why they are using them? Seems to me the most obvious and straightforward first step is to contact them and ask their story, but maybe I'm missing something...
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?
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.
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...
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...
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...
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...
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.
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...
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...
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...
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...
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...
