8th International Conference on Crack Paths An experimental evaluation of the net cross-sectional failure mechanism in Eurocode 3 for different hole configurations in presence of cracks B. (Bo) van Schuppen a , R. (Ruben) Philips a , D. (Davide) Leonetti a , H.H. (Bert) Snijder a a Eindhoven University of Technology, Department of the Built Environment, The Netherlands Abstract This study reports an experimental investigation on the applicability of the net cross-sectional resistance rules of Eurocode 3 for steel plates with different bolt-hole configurations, when short fatigue cracks are present at the edges of the holes. Previous research suggested that the design rule might be overly conservative. However, this conservativism is partially due to the potential occurrence of short fatigue cracks. Hence, specimens of steel grade S275JR were subjected to cyclic loading to induce fatigue cracks at the holes, which was followed by tensile tests to quantify the ultimate load. In addition, the failure assessment diagram is used to verify its applicability to predict the failure load. The experimental results demonstrated that relatively small cracks (<1 mm) do not significantly affect the ultimate resistance of the plates. Furthermore, the failure assessment diagram is found suitable to predict the critical condition in the presence of cracks. © 2025 The Authors. Published by ELSEVIER B.V.

Introduction Eurocode 3 (2011) provides design rules against several failure modes in steel structures, which are applicable to plain and notched components, and structural connections. Clause 6.2.3 of EN 1993-1-1 provides the cross-sectional resistance of steel elements subjected to tension. In the case of bolted connections in steel plates, the gross cross section area of the plate is reduced by the presence of the bolt holes, which cause stress concentration, making this 1.
