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.

Two Stochastic Methods to Model Initial Geometrical Imperfections of Steel Frame Structures
BuildingsThe stochastic modeling of geometrically imperfect steel frame structures requires statistical inputs for imperfection parameters, often with specific mutual correlations. The stochastic input values of geometrical imperfections are derived from European
