DOI: 10.1016/j.engstruct.2018.07.033

Abstract: Abstract During earthquakes, unreinforced masonry (URM) infills are subjected to in-plane (IP) and out-of-plane (OOP) actions. Displacement demands in the IP direction affect the OOP response to seismic accelerations and vice versa: this phenomenon is… read more here.
