In eQUILIBRIUM, the design and analysis of structures are taught through interactive, graphic statics-based drawings created with GeoGebra rather than text and equations.

Graphic statics is a powerful method for the design and analysis of structures that, by using force polygons and simple geometric construction techniques, provides intuitive visual information about the relation between form and forces in a structural system.

In GeoGebra, graphic statics constructions can be made without programming skills using the same simple geometric techniques used on paper (with pencil, ruler and compass). The elements that make up the drawing can be dynamically changed afterwards to interactively explore the relation between form and forces with real-time visual feedback.

Therefore, the combination of graphic statics and GeoGebra provides an interesting and engaging way to illustrate and explain the behaviour of structures and allows users to quickly start making their own drawings for their structural analyses and design explorations.

The purpose of these interactive demonstrations is to help you develop a thorough understanding of basic principles of structural behavior, and to provide you with tools and knowledge that will help you to design structures that are efficient and elegant.

Before you begin, you should have some familiarity with the rudiments of graphic statics. These can be learned from Zalewski and Allen, Shaping Structures: Statics (New York, John Wiley & Sons, 1998, ISBN 0-471-16968-4), and from the companion CD-ROM lessons in graphic statics by Joseph Iano (New York, John Wiley & Sons, 1998, ISBN 0-471-28338-X).

4) Advances in Architectural Geometry ( video about geometry and architecture at MIT)

CAST and the Department of Architecture co-sponsored a video that was featured at the Advances in Architectural Geometry symposium at the Centre Pompidou in Paris from September 27-30, 2012. Architectural geometry is an emerging field using geometrical principles to approach current design challenges with a renewed mathematical rigor. As part of a presentation on the most advanced and challenging research in the field, the video spotlights the groundbreaking technologies, materials, and processes produced at MIT.
