![]() It is intended for seismic analysis, but would probably do what you want. If you are looking for a structural solver, then you may want to look at OpenSees ( ), which is open source from the University of California, Berkeley. Specifically I would be looking to add orientation, sectional area and flexural stiffness to 1D entities, and thickness to 2D entities. I would be interested in hearing if anyone else has added attributes to existing 1D and 2D entities in Sketchup, and how to do it. Typically, this would involve creating models of 1D and 2D elements, which would be interpreted as beams & columns and walls and floors. I am a structural engineer and am trying to see how I could use Sketchup to build structural models. There is also a bit of info in there, on the software called MathCAD. It's not a 'cheap' book, but it's all in there, and best of all, to British Standards (BS 5268: Pt2: 1996). This book covers all the properties of timber, and their types, as well as the complex formulae needed to solve various problems- like how strong timber frame walls should be, to withstand wind pressures from various sides, and the calculations needed to have just the right amount of wood, to withstand those pressures, at the most value for money (sustainable technology), and the all the maths needed to work it all out. There is decent FEA software around, and perhaps it would be better to develop a plugin that would communicate between SU and FEA, rather than trying to do stuff from scratch? I was for a start, really impressed with an application called GMSH, but it may be too complex for architects- more for engineers, but at least SU could be used as the CAD modeller for GMSH? Perhaps the physicists (you need these guys, more than mathematicians!) at GMSH could also help with basic physics problems.įor further reading, I'd recommend "Structural Timber Design" by Abdy Kermani, published by Blackwell Science Ltd (available from all RIBA bookshops ISBN: 1-8). I think you are taking on a huge project here! I did a bit of FEA in my engineering degree, using ANSYS- but it was mighty complex.
