| FastFrame by Enercalc. This is a 32 bit Windows 95, 98 & NT Two-Dimensional frame analysis program. You can model any type of framed 2D structure by setting "joints" and specifying "members" that span between them. After loads and load cases are specified the displacements and forces are calculated by solving a bandwidth minimized stiffness matrix using an active column solver. US, SI, and Metric units. Requires 800x600 video mode using "Small" fonts. Free software. (This would have been a 5-star but for the video mode. It is still useable and I use it!) |
