Analysis of a Simplified Model of a Rigid Rocking Block on Winkler Foundation

It has been observed from previous large earthquakes that weakening the structural foundation can reduce damage of structure itself by allowing a rocking motion to release seismic energy, and this design philosophy is gradually applied new constructions. In paper, simplified model process rigid block proposed, equation derived, parameter analysis carried out. was found height–width ratio damping have great impact on response structure. On basis, combined with Winkler model, considering flexibility established. Through an example, it plays important role in overturning resistance high-rise buildings soil elastic coefficient greater higher
