Three-dimensional shock isolation device
The invention relates to the field of seismic mitigation and isolation of engineering structures, and provides a three-dimensional seismic isolation device which comprises an upper connecting part, a horizontal seismic isolation part, a vertical seismic isolation part and a lower connecting part. The horizontal shock insulation part and the vertical shock insulation part are located between the upper connecting part and the lower connecting part and are arranged independently. And the horizontal shock insulation part and the vertical shock insulation part bear a vertical load together. The vertical shock insulation part forms a vertical shear bearing for bearing pressure through a vertical partition plate and a rubber plate so as to ensure that the device has high deformation and supporting capacity under the action of a vertical load. And meanwhile, a yield energy dissipation component of the vertical shock insulation part can deform under the action of a vertical load and dissipate earthquake energy, so that the vertical damping of the device is greatly improved, and the shock insulation and energy dissipation effects are good. And the vertical shock insulation parts are distributed in the circumferential direction of the horizontal shock insulation part, and the anti-swing performance of the device can be improved. The three-dimensional seismic isolation device is simple in structure, low in cost, high in bearing capacity, reasonable in structural layout and good in overall stability, and has a typical three-dimensional seismic isolation effect.
本发明涉及工程结构减隔震领域，提供一种三维隔震装置，包括上连接部、水平隔震部、竖向隔震部和下连接部。位于上下连接部之间的水平隔震部和竖向隔震部，彼此独立布置。水平隔震部与竖向隔震部共同承担竖向荷载。竖向隔震部通过竖向隔板和橡胶板形成竖向受剪支座承压，以保证装置在竖向荷载作用下具有较强的变形及支撑能力。同时竖向隔震部的屈服耗能构件可在竖向荷载作用下发生变形并耗散地震能量，大大提升装置的竖向阻尼，隔震耗能效果较好。且竖向隔震部沿水平隔震部周向分布，还能提高装置的抗摇摆性能。其结构简单，成本较低，承载能力高，构造布局合理，整体稳定性较好，起到典型的三维隔震效果。
