Several studies on Northridge and Kobe earthquake showed that many failures were originated by improper weld details or poor workmanship. 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.
