Nonlinear static procedures are considered, at research level, the reference method for the seismic assessment of existing masonry buildings. However, at engineering practice level, the use of linear static procedures would be desirable, due to repeatability of results. The updated version of the Italian building code was released in 2018 and the review of Eurocode 8 Part 3 is going to be concluded. The aim of the paper is to analyze the outcome from the new linear static procedures and to compare it with the new nonlinear static procedures, when applied for the seismic assessment of existing unreinforced masonry buildings. This comparison is undertaken for both the new versions of the Italian and the European codes. Modelling issues such as the explicit consideration of the role of spandrels and of the flange effect will be also discussed.

Abstract
Nonlinear static procedures are considered, at research level, the reference method for the seismic assessment of existing masonry buildings. However, at engineering practice level, the use of linear static procedures would be desirable, due to repeatability of results. The updated version of the Italian building code was released in 2018 and the review of Eurocode 8 Part 3 is going to be concluded. The aim of the paper is to analyze the outcome from the new linear static procedures and to compare it with the new nonlinear static procedures, when applied for the seismic assessment of existing unreinforced masonry buildings. This comparison is undertaken for both the new versions of the Italian and the European codes. Modelling issues such as the explicit consideration of the role of spandrels and of the flange effect will be also discussed.
