The recent development of a new Italian seismic code, conceived as a transition towards the final a93d' ZE-X
adoption of Eurocodes, has been an occasion to reconsider thoroughly the current criteria for bE%mgaOh
seismic design of masonry buildings, their experimental and theoretical basis, their consequences -6*OF.Ag`
on practice. Drawing from this experience, a critical discussion of design criteria is presented, with I NFz X
specific attention to the definition of behaviour factors to be used in elastic analysis and more 8M5!5Jzv
generally on methods and models for the seismic performance verification of masonry buildings. ph5xW<VNP
Necessary and possible developments of design/assessment procedures and code provisions are O=9 V X
presented, and research needs are outlined
