A program for linear static analysis of 2D frames and trusses, with no limit on the number of nodes and members. You can build a model from scratch, import geometry from a DXF file or paste data from Excel. Besides the results themselves — displacements, reactions and internal forces — it shows the calculation steps, including the stiffness matrices, which makes it especially useful for students learning the displacement method.
