The following paper was recently published in the Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences:
Dimitrakopoulos EG, DeJong MJ (2012). Revisiting the rocking block: Closed form solutions and similarity laws, Proceedings of the Royal Society A, 468(2144), 2294-2318 (doi:10.1098/rspa.2012.0026).

During high-frequency ground motion without large impulses, rocking collapse tends not to occur. Instead, hinging induces sliding within the joints over a long duration of loading.
