Three-dimensional seismic isolation structure system

Abstract

The invention discloses a three-dimensional seismic isolation structure system. The three-dimensional seismic isolation structure system comprises a foundation, and a plurality of horizontal seismic isolation devices, a plurality of vertical seismic isolation devices, a rigid floor slab and an upper structure which are fixedly stacked on the foundation in sequence; a plurality of lateral baffles are fixedly arranged on the foundation for isolating the peripheries of the multiple horizontal seismic isolation devices, and the lateral baffles are connected with the rigid floor slab through negative rigidity connecting devices. According to the three-dimensional seismic isolation structure system, the three-dimensional six-direction rigidity self-adaptive capacity is formed through a three-dimensional seismic isolation system, so that the three-dimensional seismic isolation structure system has the capacity of isolating three-dimensional three-direction subway vibration and three-dimensional six-direction seismic vibration, and the comfort performance of a building under the action of subway vibration and the seismic safety of the building under the action of earthquakes are guaranteed.

Description

technical field [0001] The invention relates to a three-dimensional seismic isolation structure system, which is mainly used for subway vibration isolation and earthquake isolation of building structures, and belongs to the field of building technology. Background technique [0002] With the rapid development of our country's economy, traffic problems are becoming more and more prominent. The subway has become an important means to solve traffic problems due to its advantages of large capacity, fast speed, small footprint, safety and reliability; but the environmental vibration problems caused by the operation of subway trains are also It is increasingly prominent, mainly manifested in the fact that the operation of subway trains has a non-negligible impact on adjacent buildings, underground pipelines, precision instruments and equipment. In order to reduce the negative impact of subway traffic vibration, academia and engineering circles have taken various measures to reduce...
