摘要

In this paper an analysis of seismic pounding of reinforced concrete buildings with non-equal story heights including soil-structure interaction is presented. Two building configurations, configuration A: 10-story and 9-story buildings and configuration B: two 5-story buildings, are considered. The discrete model is used to incorporate foundation-soil interaction and pounding between buildings is incorporated through impact elements that consist of a gap element and a Kelvin-Voigt element. The responses of the buildings are compared in terms of impact forces, interstory displacements and normalized story shear for two near-field and two far-field earthquakes. The buildings under consideration experience the maximum impact forces and interstory displacements due to the near-field earthquakes for both fixed foundation and flexible (soil) foundation cases. Significant reduction in impact forces are observed when the underlying soil effect is considered. The maximum interstory displacements occurred when there is no pounding. In most of the cases, the consideration of soil results in lower normalized story shear.
