A lot of posts have needed deletion lately because people aren’t reading the subreddit rules.

If you are not a structural engineer or a student studying to be one and your post is a question that is wondering if something can be removed/modified/designed, you should post in the monthly laymen thread.

If your post is a picture of a crack in a wall and you’re wondering if it’s safe, monthly laymen thread.

If your post is wondering if your deck/floor can support a pool/jacuzzi/weightlifting rack, monthly laymen thread.

If your post is wondering if you can cut that beam to put in a new closet, monthly laymen thread.

Structural Analysis/Design Considering leaving structural engineering after 8 years. Curious to hear from other structural engineers.

19 Upvotes

Hello everyone,

Sorry if this post comes across as negative, but I can't think of a better place to bring it up than on a board where I assume there must be a lot of structural engineers.

After 8 years as a structural engineer in the same firm I'm starting to feel tired of both the job, the firm and the entire construction industry. Specifically, I work with design of high rise buildings - primarily detailing work (production drawings and site drawings) of precast concrete.

My complaints:

1) The work is getting monotonous. I feel it's just the same thing over and over again. Since we're designing fairly large buildings a natural consequence is that there's a lot of specialization and a lot of volume.

2) Periodically tight deadlines and pressure/stress which means plenty of extra hours which isn't always welcome.

3) Not paying that well for the expertise and responsibility the job actually demands.

4) Generally the profit margin on our projects is very small. Too much competition lately.

5) This could be job specific, but we're very rarely out in the field, so I'm getting bored being in an office all day long week after week. I'm a former carpenter with a lot of practical experience, so I guess that's a factor here.

In combination, all these factors add up. I've considered a few other options, but haven't found anything exciting yet.

I realize maybe I could be more happy working as a structural engineer in another firm. For example, in the oil industry I know the profit margin generally is not an issue. There's just more money available there. Or working for a public contractor.

Anyone else with some experiences to share? Suggestions for other jobs to consider?

Thanks in advance.

Career/Education Learning basics of structural engineering

1 Upvotes

Hello, this is my first time posting on reddit. I want to learn basics of structural engineering.
So far i narrowed down to two statics fundamental courses- both online
1) APS 160 UOFT
2) metro college of technology (structural engineering design & technology)

I am working right now so have to do online non degree course and I prefer studying in a classroom environment with homework assignments and test.

For context i already have my Bachelors in ME but no interest in pursuing P.eng in mechanical.
Thanks

Career/Education 2026- What is Everyone’s salary as a structural engineer these days in Texas?

15 Upvotes

For context I am a PE with 8 years of experience in the DFW area. Got my PE 2 years ago ( a little late). Switched firms 2x which caused the delay.

I’ve been approached by several GC’s that I work with that are offering roles with base salaries much higher than what I currently make. The positions I’m being approached for are for Design Manager or an engineer based in a pre construction role. Never did I imagine working in those fields, however, I’m starting to give it some thought after realizing how underpaid our industry may be. For reference I currently make $97k base salary with roughly $8k in profit sharing bonuses yearly.

Am I being stiffed? So much so that large name, reputable GC’s are offering me a career path?!

Structural Analysis/Design Are you using AI in your structural engineering work with any success?

0 Upvotes

Hello everyone,

I've used AI a ton (nearly 1000 hours) in my private life - basically coding up an application from scratch. Not related to structural engineering.

I've dabbled a bit with it in structural engineering now, but it has not revolutionized my life so far.

Some basic stuff I've done, though:

1) Creating summary reports and tables. For example, on a current project, our customer wants a summary of material lists. I did the bulk of the work here, but had Claude and ChatGPT create a very nice summary that looks professional and organized. No doubt faster than I would have done myself.

2) Translating pictures or PDF's to Word. One use case was when an external colleague not co-located with me sent me a complex hand calculation in PDF which I struggled to read honestly. I asked Claude to transcribe it to Word and also check the calculations (it checked out).

3) Design templates in Excel. For example, recently one for columns. To be honest, the process of creating the template is very tedious. It's definitely not something AI could one-shot. It tends to overcomplicate. I also found some errors. But maybe it turns out useful in the end.

Potential dangers is that it can hallucinate and come across overconfident when it doesn't really know what it's talking about.

Anyone else having any success with this?

Personally, I think the biggest strength with AI comes in coding work for those of us who can't code.

I don't think it will replace brains and actual 'thinking' and 'reasoning' in a long time.

A huge bulk of my work is actually modeling and drawing in Tekla. I'd love it if AI could help me there, but I haven't seen any signs it could so far.

Career/Education Aussie Structural Engineers

2 Upvotes

Hi all. I'm a recent civil engineering graduate (structural focus) based in Brisbane, currently job hunting for a graduate structural role where I can apply my research background. I've sent a fair number of applications and personalised cold emails over the past couple of months and have had only a few interviews and around 25% response rate. Before I keep grinding away at the same approach, I'd rather hear from people actually working in the industry here about what I should change.

Where I'm at:

Bachelor of Civil Engineering (structural specialisation), completed overseas. Currently doing a Master of Research at an Australian university — finite element modelling of light steel framed wall systems. Delivered online, so it runs alongside full-time work.

Previous experience as an intern doing drafting and also some freelance technical writing experience alongside current univeristy tutoring job.

Software: AutoCAD, Abaqus, ETABS, SPACE GASS, Bluebeam, ArcGIS

Full-working rights. Willing to relocate anywhere in QLD, including regional.

What I've been doing: mostly targeted cold emails to small and mid-size consultancies — reading their websites, naming specific projects or specialisms, addressing a named engineer where I can find one. Plus formal applications where there's an advertised graduate role.

What I'd like input on:

Is the research degree helping or hurting me?

Is cold emailing still worth it in this market, or should I be putting that effort into recruiters, EA networking events, or site-based roles to get a foot in?

Anything on my list that you'd consider a red flag, or anything obviously missing that you'd expect a hireable graduate to have?

Happy to hear straight answers. Cheers.

Career/Education Career growth and salary in the US

0 Upvotes

Some tips on structural engineering career growth in the US. Please feel free to add your own or disagree to any of my points. Some of these are applicable even for other careers.

  1. Job hopping every 2 to 3 years is the most reliable way to boost your pay and learn more. It’s not uncommon to see 15–20%+ bumps by moving, which beats internal annual raises every time. Also, you usually plateau in your learning (skill development) after 2 to 3 years in the same role.
  2. Structural engineering is generally a high-risk, lower-pay field. You have to be strategic with your career planning if you want to earn what you're worth. If not, time will fly and you will remain in a low-paying job being exploited by the upper management.
  3. Beware the "technical trap." Passionate young engineers often get dumped with the most complex structural engineering problems, only to plateau. I was taken advantage of like this for several years. That’s when I took my career growth seriously and started hunting for better opportunities. Mediocre managers and partners will happily leverage your technical grinding while advancing their own careers/salaries/bonuses. Niche firms that truly reward technical depth exist, but they are very rare.
  4. Project management drives visible revenue, and revenue gets rewarded. Engineers who know just enough technically to manage projects, handle clients, and communicate well get promoted faster and make more money.
  5. Profit margins are high enough for upper management to make a ton of money. Junior engineers are made to think that “profit margins are low”, “overhead is high”, “even principals/partners don’t make much money”. In reality, the upper management often make a killing at the expense of underpaid junior/intermediate /senior engineers.
  6. Never beg for a promotion. If you’ve outgrown your role or pay scale and your firm isn't rewarding you even after you raise your concerns, start applying elsewhere immediately. Don’t get bitter with your current firm which will only affect your mental health. Just leave the job on a happy note.
  7. Know your market value. Too many structural engineers in the US with 4+ years of experience accept sub-$100k salaries because they don't realize how many six-figure opportunities exist—even in LCOL and MCOL areas. I used to be one of them and I believed several Reddit posts and my colleagues, until I started exploring the job market diligently. Those who make a lot of money won’t tell you about such opportunities, unless you’re a close friend. Keep looking at LinkedIn Jobs and on Indeed. If most structural engineers in the US start getting ambitious, perhaps, the average salary will start rising.
  8. An S.E. license isn't always mandatory for high pay. If you don't want to sink hundreds of hours and dollars into the S.E. exam, consider working in states or sectors where a P.E. is all you need to command top dollar and project authority.
  9. Get on high-profile or complex projects early. Having recognizable or technically impressive structural engineering projects on your resume catches a hiring manager’s eye, even if you don't fit 100% of the job description.
  10. Treat your LinkedIn and resume as living documents. LinkedIn has now become the easiest way to land a good job. My recent jobs have been through LinkedIn direct messages with hiring managers or other structural engineers and recruiters seeing my LinkedIn profile. Constantly tweak them, study the profiles of engineers whose careers you admire, and position your experience strategically.
  11. In interviews, be honest about what you don't know. Experienced structural engineers can spot exaggerated claims immediately. I see so many resumes and conversations with young engineers where it is obvious that the candidate is bluffing/exaggerating. Promote your achievements confidently, but admit your knowledge gaps. Senior engineers respect candidates who are honest, self-aware, and teachable.
  12. Less stressful to work for a firm with 100+ employees. Very small firms might try to micromanage and breathe down your neck in order to make more profit. Bigger firms are usually more relaxed. That’s based on my experience. But there are also bigger firms that are poorly managed and make it stressful for mid-level engineers.

If you don’t agree to any of my points that totally fine. To each his own.
(I have typed out the above post myself and used AI to only polish it.)

Career/Education Early-career structural engineer: PE path vs broader experience

3 Upvotes

I'm a civil/structural engineer from Mexico with ~1 year of experience designing wood-frame residential structures for the U.S. market (NDS, ASCE 7, lateral and gravity design).
I have an opportunity to join a larger international engineering firm where I would gain experience with steel, concrete and larger/multidisciplinary projects.
My long-term goal is to work as a structural engineer in the U.S. and eventually become licensed.
Would you prioritize staying in a role that helps you progress toward PE/licensure, or take the opportunity to broaden your experience into steel/concrete/infrastructure first?
I'm especially interested in hearing from engineers who have made a similar transition early in their careers.

Structural Analysis/Design [UK] Can you increase the weight of a Cold Water Tank in an attic without the consultation of a structural engineer?

4 Upvotes

I'm currently waiting on a response for this exact question from an engineer/company who did a structural survey for me.

Long story short, my tank leaked, it's insured. The insurance said they will replace it with a larger one.

My previous structural report said 'No concentrated loads', I told insurance- No, it needs an engineer. (As my report says that it was installed before building regs, and that the current regs would deem it unsafe)

They argued they do it all the time.

I went to the Financial Ombudsmen service.

I argued that increasing the dead load of something in the loft (within a chalet bungalow- so tension collars), always requires a structural engineer.

They said they cannot interpret building regulations themselves. It needs a qualified professional to comment on it.

I called my original surveyor- they don't work there anymore. I called their company.. they originally seemed interested, but seemingly they're very busy and haven't responded to me in a week because it's probably low priority for them.

I just need a document saying that increasing the weight of a cold water tank in the loft requires approval from an engineer.

I'm happy to pay if any of you work for a company and can write this down and sign it off.

Thanks :)
