You can find many of my projects here (with the most recent on top). These tend to be larger projects. I usually post smaller projects (and news) in my blog under the respective categories.

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.

DOWEL – A Software to Simulate Dowel-Type Connectors in Wood or Other Materials

The DOWEL program is a finite-element modeler for dowel-type connections (e.g. nails, bolts, lag screws) in wood-wood, wood-steel or any other type of connection material configuration. The underlying model has even been used for pile modeling in soil. It calculates load-displacement curves for monotonic and cyclic loading applictions and plots deformed shapes at predefined displacement steps. Material inputs consist of basic material embedment data. All material data is stored in a database that can be appended by the user.

Preliminary Structural Evaluation and Presentation of Refurbishment Options for the Usher Mill in Erving, Massachusetts

This project, which was completed in the summer of 2003, was aimed at evaluating the structure of a 1918 Western Massachusetts paper mill, which sat empty and had been deteriorating for 13 years. Ultimately, the feasibility of any redevelopment on the site was to be investigated.

A New Website for the UMass Amherst Architecture Program

In 2004, the University of Massachusetts got approval to start a new accredited graduate-level Masters program in Architecture. In the process of reorganizing the existing design program in the Department of Art & Art History into the new Architecture+Design program, a new website was needed. The design of this site is based on two motifs: The strong horizontal shapes of the Fine Arts Center in which the program is housed and the square, which is meant to be a visual representation of the equal contributions of the interdisciplinary partners on campus.

Monotonic and Cyclic Behaviour of Slender Dowel-Type Fasteners in Wood-Steel-Wood Connections

The objective of this study was to investigate the monotonic and cyclic behaviour of different kinds of slender dowel-type fasteners. To accomplish this, four types of fasteners were tested in a series of 73 monotonic and cyclic tests. All tests used either one or two slotted-in steel plates in PARALLAM®, a Parallel Strand Lumber (PSL) product.
