AB  - Recent experimental tests have shown that RBS connections incorporating Jumbo specimens meet the current seismic design qualification protocols, allowing to further extend the current seismic provisions for prequalified steel connections with possible applications of heavy steel sections beyond their current use in ultra-tall buildings. The experimental results and observations described in this paper enabled a better understanding of the structural behaviour of RBS  connections  made  of  heavy  structural  sections  for  application in  seismic  regions.  How-ever, the results indicate that geometrical and material effects need to be carefully considered when designing welded RBS connections incorporating large steel profiles. To better interpret the experimental results, extensive detailed non-linear finite element simulations are conduct-ed on the entire series of tests, comprising of three large-scale specimens  with distinct sizes. The analyses intend to clarify the scale effects that influence the performance of these connections, both at material and geometric level, and particularly to understand the balance in deformation  between  the  column  panel  zones  and  the  reduced  beam  section and level  of  stress within  the  main  connection  components.  It  is  shown  that  the  numerical  models  for  all  three specimens reproduce accurately the overall load-deformation and moment-rotation time history.
