Abstract(s)
The introduction of new regulations for seismic assessment of structures established stricter performance
requirements for existing buildings. In order to account for the poor seismic behaviour of such buildings, recent
seismic codes, namely Eurocode 8 (EC8), introduce a number of prescriptions regarding issues such as analysis
type, load distribution, accidental eccentricity, etc. At the same time, these codes give room for engineering
judgment to be used with reference to the definition of structural and non-structural elements such as slabs or
infill walls, and obviously leave the modelling assumptions, such as Finite Elements typology, meshing, mass
modelling, etc. to the analyst decision. As such, four existing RC buildings, representative of traditional
Mediterranean construction, considering different modelling assumptions, were subjected to an extensive
number of nonlinear static analyses. The interpretation of possible deviations in the results will hopefully
provide indications on the relative importance of each modelling parameter or decision.
