linear and nonlinear static analysis of 3-dimensional frames
...SDL 1.2 or 2 can be used for graphics and an executable file for Window$ is included in version 2.1.0, as well as a program for analysing 2-dimensional structures, written in Sinclair BASIC for ZX Spectrum computers. A free emulator written in JavaScript, i.e. JSSpeccy v1, which was tested in FIrefox 10 from 2012 (and obviously works in all later versions), is also provided.
