Has anyone been seeing targeted ads for RISA recently? They seem to have a new marketing campaign... Which is fine, of course.
But, what's weird to me is the company seems to have changed it's name, with the woman in the ad referring to a company with a totally different pronunciation. In the...
Back in late 2021, we had this thread that discussed a feature in ETABS related to walking vibration.
thread507-489466
This thread prompted me to start an internal discussion on the topic here at CSI. I found that we were working on a new feature that would perform an analysis very similar to...

A recent death in the family (and cool post from JRB) have spurred me to begin digitizing boxes of slides from my parents and grandparents.
My Granddad took a number of pictures of the aftermath of the 1963 Dam failure. It failed after only being in service for a little over 10 years. There...
Here is an AP article on the first new nuclear plant built from scratch in the US over the last 30 years.

It cost roughly 35 Billion dollars to build. One unit is now in operation and produces...

On a related note, I just learned that my backyard neighbor is a physicist who's working on a nuclear fusion project. He loves his job, but he's a bit skeptical that we'll see true practical results...
Someone asked a question about "synthetic fuels" on another forum where we were talking about gas prices and such. I don't know much about this subject, so I thought I would ask this forum about it and see if I can learn anything from you guys.
I know that I've read about "bio-diesel" fuels...
So, I was recently informed by my homeowner's insurance that our insurance would not be renewed next year unless we replaced our existing roof.
That put me down a fairly "deep dive" on energy efficiency related to roofs and also the idea of installing solar on our roof. Eventually deciding to...
Interesting article on CNN today. I know we've seen posts about some solar projects that Bill Gates was involved in. But, it seems like he's also trying to develop nuclear as well. My favorite part of this is that it's going to a town that used to have a coal plant.... i.e. replacing one of the...
This is a relatively short news article. But, I had not read much about Carbon Capture / DAC (Direct Air Capture) before. Therefore, I found it interesting and though you all might too.

Has RISA posted anything about how the war in the Ukraine is going to affect their customers or such? I'm just curious.
FWIW, I used to work for RISA (until November 2017) and I know that a large amount of their programming was being done by the Ukrainian office. Especially for any program...
I want to say that someone commented on this in another thread. But, I can't find it right now, so I thought I'd post it here in a new thread.
Essentially, this latest experiment generated more power than the power that went into creating it. That's a pretty big step. And, correct me if I'm...
I've heard a lot about this new liquid piston engine and how it's so much more light weight than conventional engines and is 20 or 30% more efficient.
DEFINITELY not my area of expertise. I read a little bit about it. It sounds very similar conceptually to an inverted Wankel. But, instead of...
I thought I learned (way back in my college days) that the "drilling degree of freedom" for plate elements was not included in a proper plate / shell element formulation. As a work around, I have always drawn in a series of frame elements at that location to convert the drilling moment into...
I have been using the following in my structural notes for treated GluLam beams:
GluLam beams exposed to weather shall be in accordance with AWPA standard U1 to the requirements of use category A (UC4A).
However, I got an objection from a plan check engineer saying that I needed to add /...
I'm designing a small wooden bridge to span over a local storm control channel in a clients large property.
The question I have is what loading to use? Right now, I'm using 100 psf because it's a pedestrian bridge. My feeling is that is adequate for equestrian traffic as well. It's only...
I watched this YouTube video the other day and found it very interesting. I was curious what other peoples thoughts on it would be:

Concerns raised in this video regarding moving towards 100% renewable energy:
1) Transmission lines / infrastructure...
Someone I know thought it would be interesting to conduct a simple survey about what Eng-Tips users who are interested in this topic actually believe. Tough to do in a forum like this. But, maybe we can do a simple survey. I'll post a few different replies. And you merely give a star to the...
This thread is dependent on the assumption that there is a public interest in reducing carbon emissions here in the United States. That may be a big assumption for some. But, assuming it to be true, what is the most efficient way for that to be done?
To me we spend too much time arguing...
