New experimental facilities and test methods able to perform complex tests andto combine numerical and physical simulation should play an important role in theclarification of open issues in the design and assessment of structures, such asstructural irregularity, SSI, variability and type of input motions and in the study ofcomplex systems such as structures with dissipation devices, which may address theproblem of excessive expected economic losses. Performance and risk-based designshall benefit from the creation of a comprehensive database of experimental results.New measuring/recording systems, such as digital video systems to recordresponse and damage during the tests will also provide better information andevidence on local and global damage evolution and allow better damage descriptions.Assuming that performance based design is achieved, accepted and implemented,practice will move from prescriptive to performance-based codes widening thepossibilities for creativity and innovation but also transferring more responsibility tothe designer, to the owner and to other players in the process. Anticipating thatrecourse to testing and testing/simulation will be necessary, in particular forinnovative solutions, it will be required to agree on a ‘qualification procedure’,focused on standard testing protocols, which provide realistic/reliable performanceevaluation.REFERENCESFardis, M.
