FRAME3DD is a free open-source software package for static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness. It can be used to analyze frames and trusses made up of different materials, such as steel, aluminum, timber, masonry and concrete. The program is capable of computing internal forces, displacements, support reactions, and stresses in frames and trusses. It can also be used to analyze nonlinear material behavior such as plasticity, buckling and large displacement effects. FRAME3DD can be used to evaluate structural performance under both static and dynamic loads and conditions. The software is designed to be easy to use and understand, yet powerful enough to tackle complex analysis tasks. It is suitable for a wide range of engineering and scientific applications, including civil and structural engineering, mechanical engineering, aerospace engineering, and soil mechanics.
The discontinued software is not available and there is no reference to it in the official link.
