Out-of-plane seismic response of stone masonry walls: experimental and analytical study of real piers

摘要

This paper presents the application of an existing simplified displacement-based procedure to thecharacterization of the nonlinear force-displacement relationship for the out-of-plane behaviour ofunreinforced traditional masonry walls. According to this procedure, tri-linear models based on threedifferent energy based criteria were constructed and confronted with three experimental tests onexisting stone masonry constructions. Moreover, a brief introduction is presented regarding the maincharacteristics of the in situ cyclic testing recently carried out using distributed loads, as well as resultsobtained during the experimental campaigns performed. The comparison between the experimental and the analytical results are presented and discussed.
