Structural design analysis of simple steel, concrete & timber structures in 1, 2, 3…


Within 1•2•Build’s user-friendly environment, you simply draw a beam of frame structure on the screen. Next, the model is completed graphically and interactively with boundary conditions, permanent loads and variable loads.


1•2•Build does all the work for you and always delivers an optimal result: the beam with the smallest height, the steel profile having the lesser weight or the girder with the maximum deflection limits. That way you can design as well economical as fast.


1•2•Build is a complete solution which offers you all necessary functionality for optimal structural design, up to the creation of a concise and highly readable analysis report. On top of that, 1•2•Build presents you a reinforcement sketch and list of material quantities: total volume timber and concrete, total weight and volume of reinforcement, painting surface and weight of steel.
