摘要: |
Facade overturning is a frequently observed collapse mechanism occurring in unreinforced masonry (URM) buildings during high-intensity, earthquake-induced shaking. Following complete separation from a building, the rocking motion of a URM facade and the associated impact against the return walls are the factors that continue to contribute to the facade out-of-plane capacity. Seismic vulnerability studies of URM facades have historically neglected the interaction between building earthquake response and the rocking response of the facade, whereas in the study reported herein this interaction was analyzed using the discrete element modeling (DEM) approach, resulting in a facade out-of-plane capacity reduction. The increment in the dynamic rocking capacity caused by the frictional connection between the URM facade and the building was also analyzed and is reported. |
