Abstract:

The dynamic response of free standing rigid bodies to base excitation can be quite complex, as evidenced by the five motions or modes to be considered in a two-dimensional analysis: rest, slide, rock, slide-rock, and free-flight. Using steady-state slide and rock solutions, the existence of a multiple-mode response is examined in terms of the amplitude of ground acceleration and coefficient of friction. The analysis is restricted to a rectangular block with a height-to-width ratio greater than 1.
