Originální abstrakt

This paper presents a three-dimensional simple shell model for uniformly heated simply supported beam under point load considering geometrically/materially nonlinearity using the finite element analyses (FEA). The mechanical properties of steel at high temperatures were defined using the reduction factors presented by EN1993-1-2:2005. To simulate simple design rules, the thermal expansion, creep effect, and local imperfections are not considered in the proposed simple shell model. The numerical results are subjected to sensitivity studies changing different parameters including cross-section type, length of the span, loading type and boundary conditions. The results are presented in terms of bending moment resistance, critical elastic moment, and lateral torsional buckling moment at different temperature levels. The developed shell model is validated using analytical solutions.
