ABSTRACT
We hear some opinion in the architectural and construction management circles that with the development of sophisticated software the role and responsibility of structural engineers decreases. It seems that while preparing the input data only the designers do not need to know the details of structural analysis. Is it so? No, just the reverse-the contemporary structural engineer must be able to perceive and trace the software-based design progress as he always remains the creator of the structure and the expert for structural design model treated. He must take a decision over a more reliable system composition and to assess adequately the assumptions on the behaviour of elements, joints and support conditions, and to take other critical choices as regards the longterm effects for the service life of the structure. The structural engineer must have a clear view for the future at present (Huntzinger et al. 2007).
