Introduction An overview of the earthquake effects on welded structures has been conducted. Several studies on Northridge and Kobe earthquake showed that many failures were originated by improper weld details or poor workmanship. The weld is thus a fundamental variable for seismic resistance of civil engineering structures for its stress concentration effects and non negligible probability of containing a defect. Industrially, it is common to conduct a seismic analysis of a welded structure by means of a global model made of beam elements. While it could predict beams failures, the formation of plastic hinges in joint connections is dependent on the specific geometric details and their welds. Abstract Several studies on Northridge and Kob earthquake showed that many fail res wer originated by improper weld d tails or po r workmanship. A first step tow rds the modelling of w lded structure up to the weld scale has been conducted on a two dimensional mod l. A numerical feasibility analy is has b en c nd cted to assess the performance of a crit cal j int during an earthquake. In special applications, hig tolerances are needed to guarantee functio a ity. The joint is required to maintain its toleran es even after th ev t f an earthquake, he plat s are thus des gn d to remain elastic. Being a one of a kind workpiece, a numerical study is convenient to assess if the hysteresis effect is negligible. © 2020 The Authors. Published by ELSEVIER B.V.

A first step towards the modelling of a welded structure up to the weld scale has been conducted on a two dimensional model. A numerical feasibility analysis has been conducted to assess the performance of a critical joint during an earthquake. In special applications, high tolerances are needed to guarantee functionality. The joint is required to maintain its tolerances even after the event of an earthquake, the plates are thus designed to remain elastic. Being a one of a kind workpiece, a numerical study is convenient to assess if the hysteresis effect is negligible. 1st Virtual European Conference on Fracture Effect of Seismic Load on Welded Structures Deformation Romanin Luca a *, Ferro Paolo a , Berto Filippo b a University of Padova, Dep tement of E gineering and Ma agement, Stradell San Nicola 3, 36100 Vicenza, Italy b NTNU, Department of Mechanical and Industrial Engineering, Richard Birkelands vei 2b, 7491 Trondheim, Norway
