Frame3DD - Static and Dynamic Structural Analysis of 2D and 3D Frames

Description: Free software for static and dynamic analysis of 3D moment-resisting elastic frames and trusses. Written in ANSI C. Source code includes: frame analysis with elastic and geometric stiffness, LDL' decomposition, LU decomposition, Newton-Raphson iteration, sub-space iteration, Stodola iteration, static condensation, Guyan reduction, dynamic condensation, Matlab support and spreadsheet support. Graphical output and mode shape animation via Gnuplot.
