Time Histories to Response Spectrums

I have inherited an awesome project through the most unfortunate circumstances, the loss of a great engineer moving onto bigger and brighter pastures.

The project is going to be an ASCE 41 non-linear dynamic analysis and has had geotech engineers involved in picking out ground motion that represent similar ground motions that the ...

About Page Eye Candy - Javascript and Web Dev Misery

With a desire to update my "about" page, I set out to kill two birds with one stone, a fresh new about page and learning 3d graphics in the browser. https://www.re-tug.com/about/ is built with three.js, a package built within Javascript to make 3d graphics. 

Revit Addin

Making a revit addin has been a goal of mine for some time. Yesterday I finally succeeded, complete with ridiculous names, images and tasks completed.

The addin is simple and essentially useless, it assigns walls of a certain type to a workset (Github).

User Interface for Concrete Design Tool

After learning the basics of threejs for the about page, I set out to develop a web based concrete design tool. A video of https://www.re-tug.com/concretedesign/  in action is below:

Revit Rebar Bender

How awesome would it be to have an easy to use, rebar drafting drawing tool in revit, getting minimum bend radii for any type of rebar? For some reason Autodesk has never released one of these and you would think it would be easy low hanging fruit for them to tackle. ...

Revit Rebar Bender - New and Improved

Above is my first functional C# revit add-in, making bending rebar at any angle an easy task. For those non-structural engineers, the smaller the piece of rebar, the smaller the allowable bend. Being able to quickly sketch rebar to scale with minimum bend radii is ...

ASCE 41 - What Gives?!?

Lately I have found myself doing a lot of seismic retrofits of existing structures.

These buildings are often analyzed utilizing ASCE 41 and I have a few complaints with the standard that I have not found answers too... hopefully someone reading this site can help me out with these.

Ray Caster Algorithm

Now that the user interface for the concrete tool is up and running, I need to start working on the concrete analysis.

The first order of business is a meshing algorithm for the concrete shape. 

I do not know exactly ...

RAM API - Cracked

I finally cracked into the RAM Structural System API after maybe 3 years of wanting to get into it.

The key to getting in? More powerful googling. 

Googling "RAM Structural API" yields some very uninspiring result. Usually the results pointed to the RAM Structural API documentation that ...

RAM Structural API - A Practical Example

After unlocking the first part of the RAM API, I wanted to create a practical example of how this could be used to automate a few tedious tasks that we perform in the office.

The Beginnings of an ETABs Plugin

My first "Hello World" addin for ETABs is shown above. No matter how many times you see it, it is always satisfying to get Hello World to print out.

To make the addin, I followed Jeremy's examples on his website. Big thanks to him and his ...

ETABs Plugin - Part 2

Having nailed down the initial steps of creating a plugin, I set out to do some real functional work with the plugin. Being naive, I went off the deep end to begin programming the diaphragm slicer, but was quickly met by a sea of syntax ...

Diaphragm Slicer New and Improved

A long time coming... a professional level plugin for ETABs, or at least a whole lot better than the python diaphragm slicer.

User Input

This plugin will allow you to slice up your diaphragm in ...
