The R2D2-Rama 2D program is a variation of the R3D3-Rama 3D version that has most of its features but is used to perform static calculations of flat bar systems . Thanks to the convenient and transparent user interface, the program can be used not only in design, but also for educational purposes. Entering data in the program is intuitive - the geometry of the system can be defined using only the mouse. Basic construction generators are available. The program includes a library of rolled and cold-bent steel sections, reinforced concrete and wooden elements. Drawing a fairly complicated system is a matter of minutes, calculations and data presentation are carried out in real time (for small systems - up to one hundred rods). The program enables easy introduction of flat bar systems, small systems composed of several bars, as well as large 2D structures containing hundreds of bars and nodes. Thanks to this it is possible to count such construction systems as e.g. multi-storey and multi-nave frames, flat trusses, etc.
