【Abstract】 The influence of 3-dimensional(3 D) ground motion and environmental vibration on the safety and comfort of engineering structures has attracted more and more attention. How to use the three-dimensional base isolation(vibration) technology to solve the engineering problems has gradually attracted attention. Based on the relationship between vibration transmissibility and relationship between capacity and demand,the demand characteristics of three-dimensional isolation(vibration) system for isolation bearings are discussed. On the basis of theoretical achievements and scientific research practice obtained by domestic and foreign scholars,the three-dimensional isolation devices are classified based on the structural characteristics of isolation isolators,and the basic structures,applicability,composition characteristics and mechanical characteristics of different threedimensional isolation isolators are discussed.更多还原
