How much abuse can Cross-Laminated Timber (CLT) take?

Being about a month away from moving my office into a Cross-Laminated Timber (CLT) building, I am of course interested in answers to this question. As it turns out, many recent research projects proved that CLT can evidently handle quite a bit of abuse (beyond regular day-to-day loading and use)! I may be biased, but […] Read more..

Maker Faire 2012 was a blast!

My family just spent an amazing day at the 2012 World Maker Faire in New York. It was a blast! Between the life-sized mousetrap and the kids coloring a Zipcar, there was so much to see and do. What amazed me most was the fact that almost every single booth had at least one 3D […] Read more..

Hot 3D (SketchUp) models

Oh, dear – maybe the title goes a bit too far. It’s not about what you may think this is about… This really is about combining temperature and virtual 3D models of buildings. Click on the image below to get an idea of what I mean. For this project I took a lot of thermography […] Read more..

Face Centroid and Area Properties Plugin for SketchUp

A little while ago, I had a need for calculating centroids for planar shapes in SketchUp. To be more exact, my students had the need since I gave them an assignment that required this. Not knowing of a plugin for SketchUp that would accomplish this feat, they did it in Rhino or AutoCAD instead.
To rid SketchUp of this shortcoming, I decided to re-use some old Pascal code of mine and try my hand at writing a plugin for this. Here is the result.

Strength Capacities and Behaviour of a Composite Timber-Steel Connection System

This study examined the strength properties of a new timber connector that consisted of a sectioned steel tube embedded into the end grain of heavy-timber structural members using a vinyl-ester based mortar. The steel cap of the connector featured a threaded hole that allowed for the attachment of a variety of connecting steel elements.
