Hello everyone,
What does everyone think about foundations consisting entirely of isolated footings? They seem to be typical in rural areas. I've seen a lot of structures where the house itself is built like a giant wood box (with some intermediate walls throughout separating the box into...
Hello everyone,
Quick question. What do you all think of having a business’s projects archive as printing and digital backups versus no printing and digital backup only?
If I was getting a business set up and you were going to work there using your stamp to stamp drawings, would you prefer...
Hello everyone:
Quick question: what resource has all of the tables and charts for concrete design? There seems to be a decent amount of them, is there a convenient place to access/purchase them? What references are you referring to when designing concrete members?
I’ll probably be looking for...
Hello:
I’m curious to learn how I’d go about waterproofing and gasproofing design. Does anyone have any information on how to design something that is either waterproof and/or gas proof?
Hello everyone:
Simple question on beam deflections for simply supported beams only. Is the max deflection located at the point of max bending moment? If so, is there an easy to use formula for it? Or do I have to do the integral of the bending moment every time? Trying to figure out if I can...
Hello. If you look at the design values in the manufacturer’s catalog (TJ-9000) for microllam lvl, it has allowable stress for compression parallel to grain values but they are listed as beam orientation and there are no values for column orientation. Does this mean you’re not allowed to use...
When designing a moment frame what is the procedure for doing the foundation? I’ve seen people do a “rolling” (idk how to describe it) calc where they have a triangular pressure for the soil bearing. Do you know what I’m referring to? Is this the right way? Thoughts? Can someone point me in the...
Hello everyone:
I'm trying to make a mathcad prime 3.0 spreadsheet that does a standard simply supported beam calculation for me.
Some info on the file to save you time on figuring it out yourself:
Basically, what I'm trying to do is have the user input the loads on the simply supported beam...
Hello everyone,
I have a quick question on ASCE 7-16 Table 12.2-1. Note that this table is the one that lists all the different seismic structural lateral force resisting systems along with each's appropriate R, omega, and Cd values. Does anyone know of any good references that goes through all...
Hello everyone:
Is designing for temperature expansion/contraction something everyone is worried about every project? Like, do you sit there and think through every member and every piece and calc how much it's going to expand/contract and make sure all the clearances are right? Is that...
Hello everyone,
Quick question regarding framing for large steel buildings.
Do you typically use hot rolled steel for everything including floor joists? What are typical spacings? 4'-0" on center?
Or do you use hot rolled steel for just the big stuff (i.e. columns and beams) and then frame...
Hello everyone:
I have a quick question. Does anyone know of any sources/references that goes through the differences between different kinds of frames? i.e. ordinary moment frame vs special moment frame, in particular? What's the difference between these two (and others)?
Hello everyone:
The USGS earthquake hazards map that I've been using for forever to get the S1 Sds, etc. values to use in earthquake design seems to not be there anymore. They used to have a link to a different site that you could use but now the entire page isn't there and I never bookmarked...
Hello everyone,
I have some questions about the table stated in the subject of this thread.
1. What is this table referring to when it says FLOOR FILL?
2. What is the deal with the DOUBLE WOOD FLOOR loads? Do you know what exactly that means? It seems 6psf for a 2x6 @ 12" o.c. is a little...
Hello everyone,
I was looking at buying some surveying equipment but I don't do surveying that much so I'm probably going to go the cheap(er) route. Is there really that much difference between brands/quality to justify an approximately $10k difference between the low end and the high end? Are...
Hi everyone,
I have this project where the client is insisting that I do drainage and I'm a structural engineer and don't do that and I could use some input.
This is what I have at the moment. What is going on is that the contractor guessed and built a bunch of stuff w/o engineering and the...
Hello everyone,
I'm a structural engineer who is currently working on residential-type projects and I seem to be getting conflicting information about what to do when a client wants to remove a non-load bearing wall. So, say you have a contractor call you up asking you for a letter for the city...
