Abstract

ABSTRACT: Incremental dynamic analyses are performed on 48 infilled reinforced concrete buildings different for infill typology, number of storeys and design peak ground acceleration (PGA). A modelling strategy accounting for infills' interacting in-plane (IP) and out-of-plane (OOP) responses is implemented. The seismic displacement demand on buildings may be highly underestimated if the IP/OOP interaction is neglected. The PGA at the first OOP collapse is evaluated. Two-leaf infills may be not safe with respect to the OOP collapse. The OOP behaviour factor (q) of infills accounting for the IP/OOP interaction effects is determined. It is suggested assuming q equal to the unit.
