This study presents an experimental and numerical investigation into the structural collapse of a fin-plate connection due to column loss, by subjecting the joint to quasi-static and dynamic loading conditions. The joint connection was designed using short segments of HEB220 and IPE160 sections for the column and beam, respectively, with the aim to promote bearing failure as the predominant failure mode. The experimental results revealed the same collapse modes induced by shear-out failure of the beam web under both low and high loading rates. Despite the increased resistance of the joint at high loading rates, high deflections and low energy dissipation were observed. The experimental results were complemented by numerical findings from a validated finite element model in Abaqus/Explicit. Even though a good agreement between experiments and numerical simulations was achieved, the numerical model overestimated the displacement at failure due to the limitations of the customary material model. The findings of this study demonstrate the deficiencies of fin-plate connections in a sudden column loss scenario.
