The Effectiveness of Rubber Bumpers in Reducing the Effects of Earthquake-Induced Pounding between Base-Isolated Buildings

The methods for preventing earthquake-induced structural pounding between two adjacent buildings include ensuring a sufficient separation distance them or decreasing their relative displacement during seismic excitation. Some equations even specific values of such gap sizes have been introduced so as to avoid collisions. Increasing the stiffness buildings, using tuned mass dampers, applying liquid structures may reduce lateral displacements, and therefore can be prevented. On other hand, application base isolation systems result in elongation natural period building, thus increasing probability pounding. aim present paper is verify effectiveness rubber bumpers negative effects base-isolated buildings. analysis was conducted different well various thickness, number bumpers. results study show that peak impact force decreases with stiffness, Moreover, forces are reduced size. investigation clearly indicate use additional considered an effective method reducing
