ABSTRACT

The present paper deals with the comparison of values of resistance of a hot-rolled steel beam with initial imperfections. Very detailed 3D calculation models of beams were created in the computer programme Ansys applying the finite elements SOLID185. Eight nodes having three degrees of freedom at each node define the element SOLID185. Resistances were computed by application of geometrically and material nonlinear methods to the selected degree of non-dimensional slenderness depending on nominal length of the beam. Beams are subjected to bending, and their total and elastic resistance are compared with analytical, empirical and standard types of resistance.
