Geometrical and Structural Imperfections of Steel Member Systems
Procedia Engineering, 2012 AbstractThe 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.
