| 摘 要： | 将铅芯橡胶隔震垫与碟簧组合形成复合隔震垫,并应用于网格屋盖结构,利用串联弹簧模型预估铅芯橡胶隔震垫参数,利用单质点弹簧模型预估碟簧参数,结合实际工程,进行了模态分析、水平地震动时程分析及竖向地震动时程分析,表明复合隔震技术降低屋盖、下部结构加速度反应60%左右,降低由于地震引起的基顶反力约30%,但水平地震下隔震屋盖的侧移增大显著,应引起注意;文中提出的隔震垫参数预估模型得到了地震动时程分析的验证,可为工程参考。

| Abstract: | The lead-rubber bearing and the disk spring were combined to be a new composite isolation bearing,which was applied to the lattice roof structures.In the primary design,the series spring model was for pre-choosing the parameters of lead-rubber bearing,while the single spring model was for the parameters of disk spring.Jianzhen library was taken as an example for modal analysis and time history dynamic analysis respectively under horizontal and vertical ground motions.The results indicate that the composite ... |
