Experimental study into bending shear interaction of rolled I-shaped sections
conference paper
The bending-shear resistance of steel cross-sections is covered in EN 1993-1-1 [1],
taking presence of shear into account by a reduced yield stress for the shear area. An experimental
investigation on bending-shear interaction of rolled HE280A beams in S235 and S355
was performed by means of 3-point bending tests. Two criteria were considered for the evaluation
of the experimental results, being the load at which complete yielding of the cross-section
occurred and the ultimate resistance, i.e. the top of the load-displacement curve. Experimental
results complied with the design rule when the criterion of the ultimate resistance was chosen.
Yielding as failure criterion generated unconservative results for shorter beams
