These codes are written in such a legalese, I couldn't imagine referencing them in a timely fashion without my ungodly mess of notes, highlights, and tabs.
It was a gatekeeping joke.
Jokes aside though, I think more states should adopt the SE license. But some sort of PE Structural exam, easier than the SE, harder than the current PE, would be good for niche specialties. I spent a few years working in industrial in my early career where the only...
So true. I tried to pass the SE exam thinking I could just study the test, the same way I did for the PE exam. Total disaster. It wasn't until working for a different firm where I got much better experience that I was able to pass the test.
I've been saying this since the day I passed the...
You can pass the PE Civil Structural Exam by studying the test. Get the NCEES practice exam, and keep running the questions until you can do them in your sleep.
To pass the PE Structural Exam, you need to know the material, and the amount of material is enormous.
Thank you for the feedback. I'm trying to think outside the box on this one, but don't want to stamp something that stands under ultimate loads but has MASSIVE cracking and serviceability failures. I'll probably explore attaching channels to each side of the beam.
There are beams in the schedule with no stand alone top reinforcement, so I assumed the "bent bars" were to provide bottom reinforcement in the middle, top reinforcement at the ends, and have the bends located at where they anticipated inflection points to be. The issue is that with state of...
To be honest, I was black boxing this a little and chugging it into RAM Concept, but I will look into moment redistribution and see if that allows me to model and consider this RC roof as the original designers considered it.
First, I need to buy an old 1950s textbook on reinforced concrete so I can figure out what sort of design considerations these guys, or women, were making.
More immediately important though, I'm having trouble getting a 1950s building to pencil out for some new loads. The beams I'm looking at...
The line I've been using lately is that its probabilistic, and that while you may be OK with only a 1% chance your structure fails, the city is not OK with 1% of their buildings failing and that we need to follow the law.
I posed this question to both Dewalt and Hilti. Dewalt told me I didn't need to apply spacing reduction factors and they would clarify their tables in next additions. Hilti gave me more of a boiler plate answer that instructed me to refer to their table but ultimately its up to my engineering...
BAretired, I don't like using these aluminum tubes, but they are perforated all over the place for gutter and louver connections. This is one of the manufacture's details.

I think I am there, but just may have been imprecise with my language.
If I use the tube-angle built up section to carry the moment, I need the moment connection to connect to both the tubes and the angle. If I want the moment connection to only be between the post and the angle...
Eng16080, I think you just made things click for me. With the shear connection between the tubes and the angle, moment is shared. Shared, meaning there is still moment in the tubes that I need to transfer into the post.
Thank you everyone else for the input as well.
That's a good question. In retrospect, I'll need to beef up the thickness of the angle. In looking at the angle, I am considering ϕMy with 36ksi steel. If I were to consider the angle as the primary load carrying member, discount the tubes, and considering buckling, then the angle would not work.
I'm having a difficult time wrapping my head around this.
We often have aluminum tubes that connect to steel posts for our pergolas. Given the welding properties (or lack thereof) of aluminum, its been really hard to develop a satisfactory moment connection. One idea recently floated by our...
If I install some FRP at the bottom of roof beams and slabs, and 30 years from now water starts penetrating the roof and freeze/thawing between the concrete and the FRP, is there a risk of FRP delaminating from the concrete and failing?
I have used FRP on a number of projects, but now come to...
I recently picked up "Philosophies of Structural Safety and Reliability" by Vladimir Raizer and Isaac Elishakoff with the hopes there is something in this book I can use to get my points across. We'll see....
That's all I needed to hear. I've designed all of my Hilti anchors to their product specifications with factor of safety of 5, but I'm always looking to understand the products better and what options I have when I get into a pinch. When I have connections that are getting bulky and I have...
This isn't for any pressing issue, just something I'm looking to have in my back pocket if needed.
Hilti uses a factor of safety of 5. The hilti catalog says that a global safety of 4 to 8 has been industry standard for nearly three decades. Is there any scenario where you guys would use a...
