Abstract

For steel buildings and steel bridges, in most practical cases, girders are built up of hot-rolled I and H sections or welded sections. The evaluation of the actual critical bending moment for each loading pattern leads to solving a complex of differential equations so, in the design activity we use conservative and approximate equations, useful in most practical cases. The paper presents the evaluation of the bending resistance of steel plate girders with built-up cross-sections and hot rolled sections according to the Euronorms EN 1993-1-1: Design of steel structures. General rules and rules for buildings and EN 1993-1-5: Plated structural elements. An analysis regarding the influence of the load location relative to the shear center of the section and the cross-section shape has on the bending resistance of the mono-symmetrical steel plate girders is presented. A comparative analysis concerning the evaluation of the lateral-torsional bending resistance for hot-rolled I and H sections is also presented. To analyze the numerical results, a hot-rolled IPE 400 is used. Determination of the non-dimensional slenderness λLT is made using three methods: Economy method, Simplified method and Alternative method. The results obtained can be useful in the optimal design of steel plate girders.
