Several SWAT officers and U.S. Marshals suffered injuries after a porch collapsed beneath them while they were attempting to serve an arrest warrant in Missouri.
Authorities were looking for 26-year-old Jacob Muñoz, who was convicted of possessing child pornography.
Muñoz was not at the property when officers arrived, but officials say he later turned himself in.
I've come up with this issue with engineering more than one time when doing connection design, so I come here to hear from any guidance or advice with this, as I haven't found any detail showing the proper (or advised) way of detailing connections like this.
All 3 options will have a small eccentricity and a corresponding moment in one of the connecting members, but the question is, which option is the most proper for cases like this?
(I've added different colors to easy identification of members. Light gray is the plate welded to the HSS. Dark gray is the gusset plate)
i'm reviewing a floor system for a mobile unit and i'm honestly questioning my sanity
the manufacturer spec'd aluminum sandwich panels spanning 16 feet between supports. 16 feet. for a floor that's basically a glorified skateboard deck. and they're telling me it'll hold 100 psf with L/360 deflection
i ran some quick numbers and i'm getting L/180 at best. maybe i'm missing something because it's not a standard section and i don't have exact section properties. but the numbers don't add up
i asked the fabricator for more detailed info about the panel construction and they sent me a brochure. a brochure. like i'm gonna trust a marketing document for structural design
now i'm sitting here trying to make a silk purse out of a sow's ear
anyway if anyone has experience with aluminum sandwich floor panels in mobile applications i'd love to hear what deflection criteria you use. or just tell me i'm not crazy
I don't trust these things on a regular day.
I'm completely stuck on this level. I've included a few designs I tried above. Any idea how to beat this level. (Game name - Tower Builder: Earthquake Sim
Hello guys. I am planning to prepare for the SE exam as per specs after April 2027. Anyone planning the same? Please connect. We can plan to study together. Any guidance is appreciated.
Whats the easiest way to connect steel profile shs50x3 to this concrete T beam on the sloped part?
I'm in highschool and I have a mathematics project where we have to find a real life structure, that is governed by a specific principle of mathematics and develop a working model. Obviously almost every structure is based upon some basic foundational mathematics but we have to find something unique or interesting that is guided by a mathematical principle. This isn't really my expertise of knowledge so some ideas would be heavily appreciated!!
Hi everyone, I'm currently studying civil engineering in my first uni year and having some troubles understanding this concept(I'm stupid I'm sorry). Recently we did some compression test to determine the yield strength of these four bars. Now I know that buckling is a geometry problem and by the look of it, I believe the 2 long bars suffered from global buckling with the blue hollow bar buckled locally at it's top and the other one buckled in the middle since those parts aren't as strong as the rest. The other 2 bars however, suffered failure from exceeding it's yield point as they seem to bend as a whole (correct me if I'm wrong). I'm wondering if we can still determine the yield strength of the buckled examples, and is it possible to just outright determine the cause of failure of these specimens just by looking at it like I did above without relying on the datas. Thanks!
Hello everyone
I have a project for university and i need a design report for steel-fiber reinforced concrete columns (fc=45Mpa or more) and Stress–strain curves for steel-fiber reinforced concrete (tension and compression) i tried searching online but couldn't find it
Any idea where i could find that?
I submitted plans to the City for a steel frame structure that is fully exposed to the elements. They have a ban that restricts all galvanized steel (leachable metals is the actual wording). I thought this was weird since our bridge standards allow galvanized railings, etc but oh well, that’s not the point.
An alternative to galvanized steel is powder coating. I don’t want to do weathering steel, but it is an option I suppose.
The City also mentioned that there is a coating that can go over galvanized steel but he wasn’t sure what the exact name is. Anyone know what this is??
Also, the City said that galvanization is OK as long as they see a certificate guaranteeing a 50 year lifespan. I asked my fabricator and they said they can’t provide this.
US freight rail needs regulation now more than ever. Natural gas trains sit on this bridge almost everyday and video does good job showing how deteriorated it is. Am I naive to think this is egregiously unsafe or is this standard practice?
What are the questions asked by a design based company when you go for an interview as a fresh graduate? Pls help me
What is the expected salary progression for engineers who have been promoted from graduate to design engineer after 2.5-3 years of experience in larger cities like Sydney/Melbourne?
Got promoted to 80-82k base salary at a reputable mid-size consulting firm but the market seems to be pointing at 90k as the baseline nowadays.
What sort of payrise are people getting after their first promotion?
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.
Anyone here applied for pe license in VA . Can you give me rundown? I am confused
Job location- FL, salary position with 1x hourly rate paid for overtime beyond 40 hours. Working on buildings, not bridges. What is the ideal salary range for a PE who runs projects independently, act as EOR, handles billing, invoicing & client coordination. So basically handling design work, project management and admin work.
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.
Hi Structural Engineers of the USA, or Texas more specifically... I am a Structural Engineer from South Africa and I need to design a waffle slab for a site near Dripping Springs, Texas. We got the geotechnical report for the site and it's heavy expansive clays. The geotechnical engineer did recommend a reconditioning method to limit differential settlement, but I still want to calculate the slab and beam sizing, rebar and settlement in a way that would be recognised by the council. I found the PTI or WRI methods online, but not much about it. Must I use these methods or can I use FE modelling with a bearing capacity to calculate the sizing and reinforcement? Is there a specific way of calculating settlement in the US?
If I need to use PTI or WRI, does someone have a spreadsheet that you would be so kind as to share?
