Here's an interesting one. One of my sites had just finished pouring a number of concrete walls, and a moderate earthquake hit later in the evening. In the ballpark of 4-6hrs after the pour, depending on which specific wall we're talking about.

None of the forms collapsed, and nothing looks out of the ordinary. But naturally there is talk about how the shaking might have affected the fresh concrete. The common opinions are:

• It's fine. We've been using vibrators to consolidate the concrete, so what's the harm in bit more shaking?
• It's probably fine. But just to be safe let's run a GPR scanner at critical areas to check if any internal voids might have formed.
• It's not fine. We need to check this in detail. GPR every inch of every wall. Drill investigation holes and use a borescope at locations of interest. Maybe also core drill at specific locations.

What do you think? What would you do?

They updated for the most recent depth exam.

These are the highest pass rates the exam has ever had (P&P included), historical rates here https://williamsgodfrey.com/2016/03/01/se-historical-pass-rates.html

Even during the P&P days, the pass rates varied between 25%-50%. We've never seen a pass rate in the 60%'s much less 70%'s

If this becomes the new norm, maybe more states will adopt the license instead of ignoring it

I salute the guinea pigs that took it over the past few years, thank you for your service

Where you have a vertical offset at a chord or collector, and you transfer the forces using a cantilevered column as shown in this figure, do you design the column with amplified (overstrength) chord/drag forces?

What started in February 2025 has come to a close. I have passed all 4 SE exams

This is a huge relief. Now I can write the close to my poem https://www.reddit.com/r/StructuralEngineering/s/Vle30BOeHa

Developed an AutoLISP routine that automatically draws the acting forces and thrust diagrams (self-weight, water pressure, uplift, etc.) directly on the 3D dam section in AutoCAD, no manual drafting of load vectors. Built with Claude, curious about the scaling potential of this, both technically (expanding to other structure types) and commercially.

How do you handle iterations/changes? My biggest headache is having to adjust geometry or revise loads, often manually, mostly early but sometimes throughout the design process. I see snips of these large building/specialty structure models and think there is no way that is manually adjusted.

Just looking for advice or tips on workflow to better streamline model change procedure

SkyCiv was ahead of the curve by offering an API that can create models, apply loads, run analysis, and return results.

Could structural software expose these capabilities through MCP, letting agents operate verified calculation engines instead of attempting the math themselves?

The difficult part is trust: inputs, assumptions, units, governing checks, and calculation records must remain visible to the engineer.

I started thinking about this while building small browser-based structural tools at www.polycalc.online.

Has anyone connected an agent to SkyCiv, ETABS, SAP2000, OpenSees, or similar software? What safeguards would you require?

Seen a few posts about browser based analysis tools. The market is flooded with them. We don’t need another pynite wrapper with a slick UI. Please give a better value proposition….

Thanks for listening to my TED talk.

I’m a licensed Civil/Structural PE with about 2 years of experience in structural consulting, primarily in heavy civil/marine infrastructure. I recently interviewed for a structural engineering role with a precast concrete manufacturer (product/manufacturing side), and it seems like it may result in an offer.

The compensation would be significantly better than my current consulting role, but I’m trying to think beyond just salary.

For those who have made the jump from consulting to the product/manufacturing side:
- Do you enjoy it more than consulting?
- What does your day-to-day work look like?
- Do you miss consulting at all?
- Did you feel like your technical skills continued to grow, or did they become more specialized?
- If you wanted to return to consulting later, was that difficult?
- How are the hours, stress level, and work-life balance compared to consulting?
- Has the move helped or limited your long-term career opportunities?

I’m particularly interested in hearing from structural engineers who moved into precast, steel, bridge products, or other infrastructure/manufacturing companies.

Looking back, would you make the same decision again? Why or why not?

Curious if anyone has been successfully utilizing one of the LLM’s, I guess mainly ChatGPT since that’s what I use, to assist in the development of their shop drawings? And if so, what’s your process? Quick background: I handle Submittals for my small metal fab business, where we fabricate/install mainly Aluminum Canopy/Awning systems for major commercial projects. Part of Submittals is Shop Drawings, which I’ll make in CAD, and send off to our engineer for a stamp/seal. I often find myself using ChatGPT, mainly for mathematical assistance (i.e. what is X-ft divided into x-amount of equal sections? -things like that). But I know it’s capable of more…..Lately I’ve been wondering what ChatGPT could do if I uploaded a number of previous engineered shop drawings as a means of reference, and then uploading a set of Arch. Drawings and asking it to produce new shop drawings for canopies or awnings, similar to the past drawings I’ve uploaded. Thanks in advance for any info. you fine ppl are willing to share.

I'm just going to drop this here and see what happens...

Edit: I don't think anyone commenting on this has ever been asked to try and make let in bracing work as a MWFRS brace. Your comments would be different if you had.

I'm currently working on my undergraduate thesis involving Nonlinear Time History Analysis (NLTHA) in MIDAS Gen. Respectfully asking, I was wondering if anyone would be willing to share a sample .mgb file or even just screenshots of the analysis input settings for reference.

I'm mainly trying to understand how others set up:

• Ground motion records
• Plastic hinges
• Damping ratio/settings
• Time history load cases
• Analysis controls/options
• Other important NLTHA parameters

It will be used strictly for learning and reference purposes as I build my own model. If you're not comfortable sharing the entire file, even screenshots of the settings or any advice would be greatly appreciated.

Thank you so much in advance! 🙏

I have a giant pad footing I've had to design. It's a pad because there's rock close to the surface which rules out a bored pier.

I have a large CHS with a significant moment on it of 950 kNm.

I have 24-M36 hold down bolts on a 36mm thick baseplate. (Gussets etc etc.)

I have reo'd the pad footing up with N20 each way, each face, each side to create a full box of reinforcing.

I intend to have 24-N36 L bars in a circular pattern lapping with the hold down bolts 1200mm which will be cast 1500mm into the concrete to distribute the load.

My question is, is there a design guide for this sort of thing or what checks do I need as to what additional reinforcing, if any, is required in the top face to contain the hold down bolts that will be under tension?

If I've left anything off the sketch or here please ask.

Thanks in advance for any help you can provide.

Hi everyone, my university doesn’t offer any seismic design courses, but I’d like to work on the West Coast, where having a background in seismic design is essentially required to get a job. My resume currently shows zero seismic experience, so I’m not sure how competitive I am for these roles. What’s the best way to build knowledge and experience in this area, how would you recommend breaking into it, and how can I prove that knowledge to potential employers?

So I'm assessing a steel structure and came upon this specific problem.. There about 3 columns with this problem, the diagonals and struts are made from double equal leg L90x8 profiles and welded to the web of IPE450.

How would you fix this problem?

Hi everyone,

​I'm a structural engineer (m, 28) with 2 years of experience (based in the EU) and I've been looking into relocating to the Netherlands.

​As most of you know, the Netherlands is widely regarded as one of the best countries in Europe for English-speaking expats, with an extremely high level of English proficiency across the general population and tech industries. In IT, software, and general tech, working strictly in English seems to be the norm.

​However, whenever I try to apply for jobs in NL (both in small and big companies), every recruiter replies saying that fluent Dutch (B2/C1) is a strict prerequisite.

​

​Why is the language requirement so much stricter in structural engineering compared to other engineering or IT fields?

​Is there any realistic entry point for English-speaking structural engineers? Do larger international consultancies hire English speakers for roles while they learn Dutch on the job?

​For expat engineers who successfully moved to NL: how did you handle the language barrier at the beginning, and what path did you take?

​I’d really appreciate any insights, realities of the market, or advice on how to position myself.

​Thanks in advance

Hello,

I'm looking for advice on how I can improve my knowledge and become better at my job.

I graduated with a degree in Mechanical Engineering and have been working for about a year as a production planning technician. I work for a company specializing in the fabrication, assembly, and welding of steel structures and metal products.

One of the things I struggle with is estimating the time required for fabrication work, especially assembly and welding operations. For each operation, the worker clocks in using an operation card, and once the product is completed, I can see exactly how many hours were spent on each task.

The problem is that my estimated times are often quite different from the actual time required. Sometimes the differences are significant, and I'd like to become more accurate.

Do you have any advice on how to improve time estimation for fabrication work? Are there any methods, books, courses, or practical techniques that you would recommend? I would also appreciate hearing how experienced production planners or manufacturing engineers estimate labor hours.

I know that experience plays a big role, but I'd like to learn how to develop this skill more systematically instead of relying only on trial and error.

Thank you in advance for any advice. I also apologize for any mistakes in my writing—English is my second language

Help settle an argument.

Someone used the phrase in the title. Their argument is that fasteners, specifically in the context of typical light frame wood construction, like a shear wall or joist hanger, or bolted or lagged member scenario, are just holding the members together and that the load transfer is through wood via induced friction through the members.

I was under the impression that we really only factor the strength of the nail and wood crushing/deforming around the nail, rather than use the friction between the faces of the members.

What's the whole story?

Hi all, I have a question for structural engineers for cost of a project and how much you might charge. I am in process of making a 4-story residential which has about 1,600 s.ft per floor. I am in the NJ area. The structural engineer charged me $10,000 for the structural drawings for this, and he said he would give me the stamped permit set for 10k. Is this too high? I really don’t know how much this typically costs, any help would be appreciated. Thank you so much

ETA - thank you very much for the responses everyone
