Abstract (english)

The traditional construction of masonry infills adjacent to RC structural elements
is still widely adopted in European countries, including seismically active regions.
Given the repeated field observations from damaging earthquakes, pointing to unacceptably
high levels of masonry infill damage, the present study is motivated by the need to
improve further the European seismic design approach for new RC structures with masonry
infills, in order to exclude the poor seismic behaviour probably caused by deficiencies in
the verification procedure. Since the in-plane damage to non-structural panels is commonly
controlled through the limitation of inter-storey drifts, the possibility to introduce more
effective verification criteria, accounting for structural properties, infill layouts and
masonry properties is explored. Therefore, starting from the assumption that analyses and
verifications in the design of buildings are commonly accomplished neglecting the presence
of infills, results of extensive nonlinear numerical analyses for different building
configurations are examined. As a result, a simplified procedure for the prediction of
expected inter-storey drifts for infilled structures, based on the corresponding demands of
bare configurations, in function of a simple parameter accounting for structural properties
and the presence of infills, is introduced. Possible implications of the proposed approach
aimed at the improvement of the current design provisions are discussed.
