Abstract

A refined phenomenological model for masonry infill panels surrounded by R/C frames and subjected to transient cyclic loading is used to investigate the influence of the presence of regular and irregular patterns of masonry infills on the seismic behaviour of multistorey frames. It is seen that regular patterns of infills (not necessarily in all bays) can lead to a behaviour generally superior to that of corresponding bare frames. Open storeys in infilled buildings lead to damage concentration in these storeys and failure can only be avoided through heavy confinement in R/C members, as that specified in Eurocode 8. 1 Introduction One of the most common types of irregularity in buildings is caused by the uneven distribution
