Abstract
A three-storey aluminium space frame is modelled using beam elements with unrepresentative rigid joints. Five model-updating experiments are carried out using different sets of updating parameters. All of them are shown to produce improved predictions, even for modified configurations of the frame. The set of parameters that on average produces the best results is also considered to provide a physical improvement to the modelling of the joints.
