OpenSeesBf

OpenSees started with Tcl and is now riding the wave of Python's popularity. But, it's not too soon to ask which language the next OpenSees interpreter will use. In my opinion, Julia is the front runner. However, I would like to put a bid in for Brainf*ck, an esoteric programming language shown to me a … Continue reading OpenSeesBf →

Every OpenSees Tutorial

There's plenty of excellent OpenSees tutorials online. But some other OpenSees tutorials feel like this sardonic, mock programming tutorial. When you watch the video, replace "outdated library" with "OpenSees", "Java" with "Tcl", and "Minecraft" with "incremental dynamic analyses for a portfolio of 3D reinforced concrete frames". https://youtu.be/MAlSjtxy5ak Pretty accurate, right? Let me know in the … Continue reading Every OpenSees Tutorial →

A Blog in Motion

It has been two years since the blog's first post, which was neither interesting nor informative. Since then, the blog has become unstoppable. Not unstoppable in the Michael Jordan in the NBA Playoffs kind of way, but in the sense that momentum makes it difficult to stop posting. Until that time comes, here are summary … Continue reading A Blog in Motion →

Non-Fungible OpenSees

The latest spam to creep into the OpenSees universe has come from digital artists looking to sell their NFTs (non-fungible tokens) to members of the OpenSees Facebook group. The art is sold through the NFT marketplace, opensea.io, so I can see the confusion with OpenSees. Before the group admins remove the NFT posts, I ask … Continue reading Non-Fungible OpenSees →

Backlink Hijinks

The OpenSees message board is kind of a mess. Not due to posters, responders, or moderators, but because of the huge amount of spam posts. I've seen various forms of message board spam including offers for cell phone numbers, online games, and refrigeration equipment, as well as some spam that's NSFW. Removing all the spam … Continue reading Backlink Hijinks →

Striking YouTube Gold

It's been a busy week, one in which I have not managed my time very well. While 71 posts sit in my Drafts folder, I haven't sat down to get one to the finish line. So, why not add more to the Drafts folder? While the history and use of reliability modules in OpenSees will … Continue reading Striking YouTube Gold →

Syllabus by Blogging

Since joining the faculty at Eastchester, I've taught nonlinear structural analysis many times. The course content is shaped by what I learned, and continue to learn, from Frank, Greg, Filip, and Silvia. The blog is another outcropping of what I've learned. So I've integrated many of the posts into the course, which consists of the … Continue reading Syllabus by Blogging →
