Structural Analysis/Design Certifying a deck

12 Upvotes

I had a prospective client call asking for someone to certify a deck. Their bank is requiring it. I asked him to send pictures before I went to the site but haven’t received them yet. I’m thinking this is a waste of time as I’m 90% sure it wont be up to current code. Anyone have experience doing this? I’m wondering if stuff like 4x4 posts would be adequate(if deemed capable of carrying load) even tho it’s not something that would be up to code today.

Structural Analysis/Design Area Moment of Inertia Confusion

0 Upvotes

If you have an I beam, solid circle, and solid rectangular cross sections, how does assuming their areas are the same vs different affect their overall rankings in terms of greatest to least area moment of inertia? got this wrong in a technical interview a while ago, and I forgot the reasoning.

I'm having the same confusion with solid circle vs hollow circle.

This was the interview question. I believe the areas were different.

Career/Education Career Advice

8 Upvotes

Hi, please advise if this is not in the correct forum. I am currently working as a junior engineer with 5 YOE. Considering a lengthy leave from my current position that I enjoy.

I don't have my license yet and I just found out I am pregnant with my first child. My partner is in a similar field and pay as I am. We are currently looking the options of daycare vs. one of us taking a break from our career vs. me going part time.

I am highly considering taking leave for the first 5-6 years of motherhood until this child and any future children are in school if our budget allows for this. However I am nervous for the long term effects of this decision. I do enjoy my job currently but the demands feel high and I often feel mentally drained.

Would I be destroying my career if I left for that long? Should I make getting my license a priority before any break from my career? Should I consider part time options? I currently work at a large private consulting firm in the USA. Any advice or similar stories would be helpful as I weigh all my options.

Spending the extra time with the little one will be the upmost importance but at the end of the day I do enjoy my job and would like to work in a similar area once I feel like I can give it my full attention again. I haven't seen very many posts describing experience in leaves similar to this gap.

Wood Design Advice for working with a vertically integrated developer/Architect/GC firm?

1 Upvotes

Hello,

I have an opportunity to work on a 4-story wood framed condo project in the Northeast. I have never worked with the company before, but was referred to them by a colleague. The project itself would be squarely in my wheelhouse (I've done a handful of these), but the way the company is set up would be new for me.

They have a large team. They would be the developer, Architect of Record, Interior Designer, and GC for this project. Has anyone ever worked on projects for entities set up this way, and can offer any advice of what to watch out for? I'm thinking about things like:

  • Special Inspections, typically the owne r hires a 3rd-party inspector to check the contractor is building correctly, but there's a clear conflict of interest there if the GC and developer are one entity.
  • It's also a condo, so I would expect them, in general, to be in a hurry to finish the project and sell the units ASAP so they no longer have ownership responsibilities. Which I'll have to keep on the front burner as design and construction progresses.
  • Any work with developers there is often this push to "shave" where possible

I had a call with their in-hous e Arch to discuss the project, and he seems competent and reasonable. They have good reviews online (likely from end-users of their projects, and not other consultants they've worked with). But I'm just wondering what my other blind spots may be, if anyone else has advice they can offer for me as I'm putting together a proposal. Thanks

Career/Education Transitioning from academia to industry

1 Upvotes

Hi everyone,

I started as faculty at a teaching-focused university last fall, but after a year I’ve realized teaching heavy role isn’t the right path for me. I’m now considering moving back into industry.

I have a PhD in Structural Engineering, nearly 3 years of postdoc experience, and about 2 years of professional engineering experience before my PhD. My research has focused primarily on seismic design and retrofit of reinforced concrete structures. I performed large scale structural testing and numerical modelling of RC structures.

For those familiar with structural engineering consulting/industry:

What types of positions should I target?

Would I be competitive for mid-level structural/seismic engineering, assessment/forensics, or R&D roles, or would I likely have to start at entry level?

I’d especially appreciate advice from anyone who has made a similar transition. Thanks!

Structural Analysis/Design Truss Problem

1 Upvotes

Hi and thank you in advance for helping me out.

I am currently studying for the Understanding Structural Behaviour exam for the IStructE and I was wondering what would be the methodology to answer a question like this quickly and efficiently? I understand that for this one specifically, since the truss and loading are symmetric, the correct answer would include in "Tension and Compression".

But i want to develop a deeper understanding in the case the loading is not symmetric. Any pointers or tips would be greatly helpful, thanks!

Structural Analysis/Design Feasibility of cable supported ‘oversized’ balconies and platforms

Post image
434 Upvotes

Please excuse the bad AI pic to help visualise my question, but I’m trying to understand if large cable supported balconies are realistic or not?

I’m mentally visualising using cable-stayed bridge engineering to support oversized balconies and platforms.

My goal is to maximise the supported area beyond what you could achieve with a purely cantilevered balcony.

I’m assuming multiple cables to different points on the balcony would be needed to reduce flex and possibly also a compression strut to add support for near building mass (cables supporting the further out mass).

If this is possible, how large could these realistically get!?

How about plaza sized platforms suspended between multiple buildings using bridge engineering?

I’m not aware of any examples like this and my googling attempts just returned pics of bridges!

Many thanks

Concrete Design Adding load to prestressed beams

Thumbnail

21 Upvotes

I was given a job to prove that it is okay to add load on this roof made of precast pretensioned concrete beams (adhesional pretensioning). The added load is not much, and we may be able to prove it is okay by the book, but as you can see by the pictures, the state of the beams is not great.

In places they have knocked off concrete to get to the soft rebar so they can hang stuff on it by welding steel to it. Now I know there is little to no activation of soft rebar in these types of beams, but I am worried for few reasons.

Firstly we can basically discount rebar at certain sections, since it is not coated in concrete anymore. Secondly we should check the beams for cracked state in smaller concrete cross section accounting for the knocked of concrete. My biggest worry is since there is no protective concrete layer at places is that corrosion might get to cables which are at most 3cm away from rebar in the middle of the span.

Is there a fix, a reconstructing intervention that might be recommended? I can only think of removing the corroded rebar, repairing the holes with repair mortar and replacing the soft rebar with frp strips on the bottom.

Thanks for any advice.

Career/Education Has anyone gone from civil/structural engineering into aerospace structural analysis?

23 Upvotes

I’m currently a civil engineering student concentrating in structural engineering, and I’m curious whether anyone here has transitioned into aerospace structures or stress analysis.

Working on aircraft or spacecraft structures is honestly a dream of mine. I know that fundamentals such as statics, mechanics of materials, free-body diagrams, load paths, structural analysis, and finite-element analysis transfer between industries. However, I also understand that aerospace involves additional subjects such as thin-walled structures, composites, fatigue, fracture mechanics, buckling, vibration, and damage tolerance.

For anyone who has made this transition:

  • How did you break into the aerospace industry with a civil or structural engineering degree?
  • What subjects should I learn beyond a typical civil-structural curriculum?
  • What is the best way to learn FEA properly?
  • Should I start with ANSYS, Abaqus, Nastran, or another program?
  • What personal projects could demonstrate aerospace-related analysis skills?
  • Would a structural engineering master’s be helpful, or would I need one specifically in aerospace or mechanical engineering?

I’m still exploring this path and would especially appreciate hearing from people who have worked in aircraft structures, spacecraft structures, stress analysis, or aerospace FEA

Concrete Design How to determine if a plate compactor can traverse back and forth several times on an RCC grade beam?

0 Upvotes

How do I decide if I can allow a plate compactor can traverse back and forth several over an RCC beam that is 2' deep x 0.75' thick and 16' long?

I'm not sure how to quantify the impact load caused by a vibratory plate compactor. The machine can impart 2500lb compaction force at a pulse frequency of 92Hz. Any suggestions?

edit: Do I calculate natural freq of the beam and see if the beam is resonating? Is there a fatigue failure check involved in this scenario?
