Geometrical and Structural Imperfections of Steel Member Systems

The paper is focused on the influence of geometrical and structural imperfections in selected load-bearing steel structures from the point of view of the whole load-bearing system. Implemented member steel structures show a varying degree of shape and structural deviations from the presumed idealized state. As a rule, these imperfections arise in manufacture of the structure, its assembly and in use of the structure. These imperfections can have a considerable impact on the structure behavior. Impact analysis of these imperfections is made using selected examples of particular types of load-bearing steel structures as for their load-carrying capacity and serviceability.
