A three-dimensional seismic isolation structure system

Abstract

The invention discloses a three-dimensional shock-isolation structure system, which includes a foundation, on which a number of horizontal shock-isolation devices, vertical shock-isolation devices, a rigid floor and a superstructure are sequentially fixed and stacked; A number of side baffles are fixedly arranged on the surrounding foundation, and the side baffles are connected with the rigid floor slab through a negative rigidity connecting device. The three-dimensional seismic isolation structure system provided by the present invention has the self-adaptive ability of three-dimensional six-direction stiffness through the three-dimensional seismic isolation system, so that it has the ability to isolate three-dimensional three-directional subway vibration and three-dimensional six-directional seismic vibration, and ensures the stability of the building under the action of subway vibration. Comfort performance, and seismic safety of buildings under earthquake action.

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...

AI Technical Summary

Problems solved by technology

At present, the application of three-dimensional seismic isolation devices in building structures along subway lines faces the following challenges: it is difficult for three-dimensional seismic isolation devices to have the ability to isolate subway vibration and earthquake vibration at the same time; The further improvement of overturning capacity is still the bottleneck restricting the development of 3D seismic isolation technology
