 abstract={Block tearing is a failure mode of steel connections based on rupture of material. In this paper, a numerical model is developed to capture fracture initiation and progression until failure in steel angles connected by one leg using single row of bolts. It was realized using Gurson-Tvergaard-Needleman porous material model, which can accurately trace the behaviour of steel at plastic and ultimate range. Obtained results are validated on laboratory test results in global and local terms. Stress distribution along the failure paths in the gross and net area subjected to shear and tension was investigated for different geometrical arrangements of connections. Observation of rupture mechanisms allowed to compare the design procedures given in Eurocode 3 with connections behaviour. Results of analysis indicate that both plastic stress distribution in gross shear area and ultimate stress distribution in net shear area can limit block tearing resistance, which is consistent with the newest code provisions.},
