摘　　要：提出并设计了一种新型组合式三维隔震支座(3DIB),该支座由铅芯橡胶支座(LRB)和组合式碟形弹簧竖向隔震支座(DSB)组合而成,并进行了性能试验。性能试验结果表明,3DIB具有与LRB类似的水平特性、与DSB近似的竖向特性。3DIB具有可变的水平刚度与竖向刚度,水平等效阻尼比与竖向等效阻尼比均达到20%左右,并且具有较高的承载力,可以用于建筑结构的三维隔震。A new style base isolation device, which is called combined 3-dimensional isolation bearing （3DIB）, paper. 3DIB is composed of lead rubber bearing （LRB） and disk spring bearing （DSB）. In order to verify the 3 is introduced in this D performance 3DIB, several performance tests are conducted. The results show that the LRB is used for horizontal isolation and the DSB vertical isolation, the horizontal properties and vertical properties of the 3DIB are determined by LRB and DSB, respectively high load capacity, variable stiffness and high damping, the 3DIB can be used in 3-dimensional base-isolated buildings. of the is for With
