Originální abstrakt

A number of full-scale plate girders are modeled and analyzed to determine their bending and shear failure mechanism characteristics. The design of a thin-walled system is always rather complicated as also the influence of initial imperfections is to be taken into account to a greater extent. The theoretical analysis was based on a nonlinear variant of the finite element method, the girder being modeled by means of shell elements, and the ANSYS programme being applied. All input imperfections were considered to be random quantities. The statistical distributions were introduced according to both experimentally obtained results and data given in literature. Random realizations of input random quantities were simulated by the LHS (Latin Hypercube Sampling) method. By means of sensitivity analysis, it was studied to what extend the variability of initial imperfections was reflected in the variability of stresses in the crack-prone areas of the girder.
