Nowadays, prequalification criteria for seismic resistant beam-to-column joints are missing in Europe. In addition, specific requirements and design rules for these joints are not provided by Eurocodes, which gives rules only for non-seismic joints, even though dissipative joints are allowed by EN1998-1, provided that their effectiveness is verified by testing. Obviously this approach results in expensive and time-consuming design, due to the lack of reliable analytical tools able to predict the seismic performance of such connections. In order to overcome such limitations, the EQUALJOINTS research project aimed at developing a prequalification procedure for bolted joints typically used in the EU practice, i.e. haunched, extended stiffened and unstiffened end-plate joints. In addition, welded dog-bone joints with heavy profiles are also investigated. Design tools and prequalification charts have been provided on the basis of experimental, numerical and analytical investigations. Those include general requirements, limitations, design procedure and qualification data.
