The following report describes one laboratory experiment which consisted of two parts. The first part of the experiment was to examine how bending moment varies with an increasing point load. The second part was to examine how bending moment varies at the cut position of the beam for various loading conditions. From our results it was concluded that for the first experiment when the load applied on the beam was increased, the bending moment will also increase. This indicates that, bending moment is linearly proportional (positive) to the load apply on the beam. This linear proportion can be noticed on Figure 1 of this report. However, there was a small percentage of error that occurred during the experiment which yielded slightly different experimental to theoretical values. This had an effect of the graph slightly. As for the second part of the report the bending moment at the cut is equal to the algebraic sum of the forces acting to the left or right of the cut was proven to be accurate. Hence, the objective of this experiment is proven and our experiment achieved the objective.

Laterally and torsionally unrestrained steel I-section beams are susceptible to torsional deformations between supports; therefore, according to Part 1-1 of Eurocode 3, they need to be designed to resist lateral-torsional buckling. Eurocode's steelwork design criteria require safety checking based on two stability interaction formulae utilizing the so-called equivalent uniform moment factors and the cross-section resistance formula that, in the case of moment gradient, refer to the beam end section. Uncoupling the beam stability resistance criterion and the cross-section resistance criterion may result in a nonuniform safety assessment of I-section beams. Finite element simulations of the beam resistance for different moment gradient ratios are performed. Verification of the buckling resistance is conducted by varying the following parameters: the slenderness ratio, the location of maximum end moments about both axes and the section depth-to-width ratio (i.e., considering rolled I-and H-sections). The variation in the accuracy of the current Eurocode resistance evaluation method is identified, and an approach for a better equalization of the safety predictions is suggested by considering different values of the most important factors influencing the stability performance of steel I-section beams.
