摘要
为了研究锥形非固结隔震支座的水平力学性能及滞回特性,设计并加工了坡度角为30°、45°及60°的锥形非固结隔震支座,对9个不同参数的支座进行水平力学性能试验研究,对坡度角、阻尼材料类型、阻尼材料厚度、加载振幅、加载频率、竖向荷载及高应力等与支座的水平力学性能的相关性进行研究,得出若干对非固结隔震结构设计有价值的结论。
Tapered non-consolidation bearings with slope angle of 30 °,45 ° and 60 ° were designed and tests of nine bearings with different parameters were conducted to study their mechanical properties and hysteretic characteristics here.The mechanical properties of the bearings with different parameters including slope angle,type of damping material,damping material thickness,loading amplitude,loading frequency,vertical load and high stress were studied.The valuable conclusions were obtained for a non-consolidation isolated structure design.
