Embodiment 1

[0033] Example 1 as figure 1 , 2 As shown in and 3, the anti-seismic and resilient plant structure system of this embodiment comprehensively adopts the shock-absorbing technology, mainly including a large mass ratio tuned mass damper 1 connected to the main structure of the plant and an energy-dissipating sub-frame 2 containing the damper.

[0034]Through the design, the coal hopper equipment in thermal power plants is designed as a large mass ratio tuned mass damper 1, which mainly includes a coal hopper 3, an isolation layer 4, and a support system 5. Wherein the coal hopper seismic isolation layer 4 includes a horizontal seismic isolation support 10 and a horizontal limiting device 11 . Support system 5 comprises polygonal planar frame structure 9, and the number of sides of polygonal planar frame structure 9 depends on specific circumstances, and polygonal planar frame structure 9 is an octagon in the present embodiment, as image 3 shown. Each side of the polygonal pla...

Abstract

The invention belongs to the technical field of industrial civil structures, and relates to a high-performance toughness structural system comprehensively applying seismic solation and energy dissipation seismic absorption technologies to improve anti-seismic performance of a plant. The anti-seismic toughness plant structural system comprehensively adopting seismic isolation and absorption technologies comprises a large-mass-ratio tuning mass damper and an energy dissipation sub-frame which are connected to a plant main structure. Buckling-restrained braces are adopted to replace parts of ordinary steel supporting components, and the damper is adopted on a structural floor with large horizontal relative displacement to replace an ordinary supporting structural system so as to achieve the effect of energy dissipation seismic absorption; a coal hopper of the plant is subjected to seismic isolation design through a seismic isolation support, the adopted seismic isolation support is optimally calculated, and thus movement of the coal hopper under the seismic effect and movement of the main body structure are tuned to form the large-mass-ratio tuning mass damper; and the anti-seismic toughness plant structural system can be applied to structural design and seismic reinforcement of the high seismic intensity field underground plant, and can also be applied to other similar industrial structures.

Description

technical field [0001] The invention belongs to the technical field of industrial civil structures, and relates to an anti-seismic tough factory building structure system, which can be applied to the anti-seismic design of factory buildings and the anti-seismic reinforcement of existing factory buildings. Background technique [0002] Earthquakes are sudden and unpredictable, and destructive earthquakes may occur at any time. These earthquakes will not only cause huge casualties and property losses, but also cause serious secondary disasters. The Wenchuan Earthquake in 2008 caused great harm to our society and economy. Previous earthquake damage shows that the collapse of buildings is the main cause of casualties and equipment damage. Therefore, how to improve the seismic performance of engineering structures is a major task in the field of engineering structure research and engineering construction in my country. [0003] According to the requirements of the process syste...
