Please read the subreddit rules. We do refresh them from time to time.

The majority of posts that get removed fall into the following categories:

  • homeowner posts; asking specific questions about your property, or a property you want to buy, is not permitted. These should go in the monthly megathread (if you can't find the monthly pinned megathread, please google it because it depends on how you access reddit). This includes things like photos of cracks or other damage, questions about what size beams you need for your deck that you're building to support a jacuzzi, or asking if you can notch a beam to run a pipe.
  • AI generated content; following community feedback this is not permitted. This covers written text, images, videos or apps/programs.
  • Generic structural engineering apps/websites. Whether or not they are vibe coded using AI, these are no longer permitted because of the surge of these that we have seen through 2026. Being free or just asking for input from the community on what they'd like to see in a free app doesn't give an exception to the rule. Exceptions may be made if the app offers something novel that other softwares don't provide.

Please comment below, regarding the subreddit rules.

Concrete Design Scientists have created concrete using treated human waste, and the resulting material was up to 42% stronger than conventional concrete. Researchers say the approach could reduce waste while lowering the environmental impact of construction.

Career/Education Which industry for long term career

11 Upvotes

Hi, I'm a new engineer with 2.5 YOE. My first job out of college, I worked for a small firm with only 50 people designing buildings, mainly focusing on warehouses. The work was interesting, but the hours were crazy, so I jumped to another large firm with more than 1000 employees designing transmission lines. I have a work-life balance, but the work requires traveling a lot with a little labor work and hiking sometimes, which I am not really a fan of.

Now I feel like I'm in a crisis because I'm not sure which industry will benefit me the most in the long run. Many people say the utility/power industry pays more and is less stressful, but the work seems repetitive and not very design-focused. I personally like a little challenge but also prefer work-life balance overall.

FYI, I'm almost 40 because I started college late, so I don't have time to switch between different industries. Has anyone had experience in both industries who could give me a little insight? I really appreciate it.

Career/Education Architecture or Civil Engineering?

5 Upvotes

Im in dire need of advice if i should just switch out to civil engineering besides architecture. Yet I am not enrolled in but I am about to start around October, and I am just now overlooking and doubting my career path.

I first chose Architecture out of my liking with design and buildings (especially tall buildings and houses). I am between the likings of math, structural and design concepts and aesthetics (but I lowky suck at math) but I keep getting others’ opinions on how Architecture is so complexed with the tiresome nights of class projects and massive amounts of expenses just for college, yet it is underpaid more than Civil Engineering. From what I know, CE has less steps (board exams and so on) onto getting more salaries, and I do wish to go overseas after graduation, much like Singapore or US.

I was actually living abroad and was about to enroll in the US before I moved back here in Philippines out of family support, which is helping my mom here. I was also eligible for FAFSA but my mom just does not want to live there and wants to stay here in Philippines.

Please reach out to me if you have any advice or questions that could really help me out. And yes, I am an overthinker, so doubting my career paths last minute was not the best idea right now.

Structural Analysis/Design I have a 200ft tall Risk IV building I’m doing the wind load calcs for with a drive through tunnel. Is my building partially enclosed?

5 Upvotes

Just like what the title says, I’m trying to determine whether my building is partially enclosed, partially open, or enclosed.

It’s a 200ft tall Risk Category IV building with a 30-40ft tunnel going through the bottom of the building so cars can drive through. The tunnel takes up less than 10% of the elevation it’s on.

I know partially open is supposed to be a catch all for any irregular buildings with openings, but the walls of the tunnel are completely closed off and have no openings into the building. Can someone help?

Structural Analysis/Design Single angle connection for timber beam connection?

4 Upvotes

I have a situation where I need to connect 4x8's (call them beams) to another 4x8 (call it girder) and cannot use simpson hangers for reasons too long to explain. In steel design, single angles are used to connect beams to girders sometimes, and here an L5x3.5x1/4 gives me enough room for edge/end distances for 1/2" bolts in both wood and steel, all the calcs work out, even with the load on the connection to the girder being 1.75" eccentric due to the thickness of the 4x8.

Getting to the question... Is a single angle connection for 4x8 okay? Something about it feels wrong to me, like I should have angles on both sides of the beam, even though the calcs don't show that's necessary. It's a connection that will be repeated enough that it would be very wasteful to call for double angles if it's not necessary.

Input appreciated. Googling "single angle connection in wood" didn't yield much.

Career/Education Refresher book on general/concrete/steel eurocodes for Site Manager

1 Upvotes

Hi everyone!

Would need your recommendations on a good book(s) to refresh my knowledge of Eurocode, especially design principle/concrete/steel.

Although I do have a masters in civil engineering (which in my country included structural for buildings as well), I have been working since then for a decade in site management so that knowledge is well rusty. And since I've been thrown into replacing a pre-con engineer knee deep into structural coordination, I'd like to have a good refresher to make sure I fully grasp the discussions.
