Seismic Vulnerability Assessment and Strengthening Interventions of Structural Units of a Typical Clustered Masonry Building in the Campania Region of Italy

The present paper aims at inspecting the structural behaviour of a typical masonry aggregate located in historical centre Cercola, municipality province Naples. clustered building under study consists four units mutually connected to each other made tuff stone and deformable floors. Two distinct units, namely heading intermediate places, both isolated conditions, are examined estimate influence positions on global seismic response case buildings. For this purpose, non-linear static analyses performed using 3MURI software. Pushover conducted evaluate improve their earthquake performances while considering proper retrofit interventions vertical horizontal structures. analysis results plotted terms risk factor, stiffness, ductility. Finally, set fragility functions derived point out buildings before after interventions. From achieved results, it is highlighted that buildings, especially those conditions.
