Variable-stiffness self-resetting three-dimensional shock insulation support
The invention relates to a variable-stiffness self-resetting three-dimensional shock insulation support which comprises a friction pendulum shock insulation mechanism which comprises an upper support plate, an upper sliding plate, a core sliding block, a lower sliding plate and a lower support plate which are sequentially arranged from top to bottom and are in sliding friction contact pairwise; the vertical self-resetting shock insulation mechanism comprises a bottom plate, a pressing plate, a vertical shock insulation support and a vertical self-resetting assembly, wherein the pressing plate is located above the bottom plate and fixedly supports the lower support plate, and the vertical shock insulation support and the vertical self-resetting assembly are located between the bottom plate and the pressing plate. Compared with the prior art, the three-dimensional seismic isolation support is simple in structure, clear in force transmission and high in bearing capacity, different horizontal and vertical rigidities are achieved under the action of earthquakes of different levels, the earthquake and vibration double-control target of multi-level performance can be achieved, the post-earthquake repair cost of the structure can be effectively reduced through the three-dimensional seismic isolation capacity and the self-resetting capacity of the three-dimensional seismic isolation support, and the three-dimensional seismic isolation support is suitable for large-scale popularization and application. And the overall shock resistance toughness of the structure is improved, and wide application prospects are achieved.
本发明涉及一种变刚度自复位三维隔震支座，包括：摩擦摆隔震机构，其包括从上到下依次布置且两两之间呈滑动摩擦接触的上支座板、上滑板、核心滑块、下滑板与下支座板；竖向自复位隔震机构，其包括底板、位于所述底板上方并固定支撑所述下支座板的压板、以及介于所述底板和压板之间的竖向隔震支座与竖向自复位组件。与现有技术相比，本发明三维隔震支座构造简单，传力明确，承载能力强，在不同等级地震作用下发挥不同水平和竖向刚度，可实现多级性能的震、振双控目标，其三向隔震能力和自复位能力可有效减少结构震后修复成本，提高结构整体的抗震韧性，具有广阔的应用前景。
