About

Welcome to Building<code>! This site is a side-project/hobby I started for fun. I'm a professional structural engineer with 15 years design experience in the U.S., but I've enjoyed computer programming since high school. This site provides a few basic structural engineering web applications for free use.

By using this website you agree to the User Agreement below. To report errors see Reporting Errors below.

The site is a little bare right now, but I am improving it. You can expect to see continued improvements to the site and more tools to come, so please check back regularly. Don't expect these tools to check everything for you or to be free from errors. I am working to make the calculations more transparent so you can validate them yourself manually. If you see an issue please report it (see below). I hope you find these tools useful.

Basic Usage

The tools on this website all work similarly. When you click the User License Agreement checkbox a button will appear on the right allowing you to run the calculations.

Errors will either appear in red directly in the forms you fill out, or they will appear at the bottom of the screen in red. Calculations won't be able to be run until all errors are resolved.

If you want to save your work and come back to it later you can use the "Save File" and "Upload File" buttons in each tool. Files will download from your web browser in .csv format, and you can upload them back to the site to pick up where you left off.

The calculations are printer friendly. Simply use your web brower's printing capabilities to print any of the calculations. The calculations are divided into sections. If there is a section you don't want to print, simply click on the section heading to toggle it. If it's toggled off it will not print.
