Introducing TwoDFrame

TwoDFrame ('2D-Frame') is software for the structural analysis and design of two-dimensional frames. If statics or dynamics, first or second order analysis, beam or column design, reinforced concrete, structural steel, or structural timber design: TwoDFrame always serves its users with a customised and relevant solution.

TwoDFrame is completely integrated within Microsoft Windows and is continuously adjusted to new Windows versions. All source code is written by us and is brought into line with the constantly changing requirements of new codes of practice. Therefore, TwoDFrame stays relevant and has a guaranteed future.

TwoDFrame can easily be used in multi-language projects or working environments. It even can serve as a major communication tool for engineers working from different countries on international projects. Therefore, TwoDFrame is an active contribution to build a single European / World market.

TwoDFrame features a powerful graphical user interface unmatched in terms of ease-of-use and productivity. Creation and modification of the structural model, running the analysis, and checking and optimisation of the design are all done with the same interface. Structural analysis results are always at the structural engineer's fingertips. Armed with TwoDFrame, structural engineering becomes a delight.

Enjoy!
