The extension of the use of Nonlinear Static Procedures (NSP) to the case of irregular structures has so far been the object of only restricted scrutiny, which effectively ends up by limiting significantly the employment of NSPs to assess actual existing structures, the majority of which tend to be non-regular. In addition, such few studies have typically concentrated on the application and verification of a single NSP approach, thus not providing useful elements of comparison between the different methodologies available... An important contribution to an increase in the effective application of these procedures to 3D irregular structures can perhaps be obtained by intensifying the exchange of research results, ideas and experiences. A national research project on this topic, constituted thus a step in this direction... For the considered nonlinear static procedures to 3D irregular structures, the scientific issues open to research in this project are summarised in the paragraphs..
