Function-recoverable giant framework structure with vibration absorption sub structure

Abstract

The invention discloses a function-recoverable giant framework structure with a vibration absorption sub structure, and belongs to the technical field of vibration absorption control. According to the function-recoverable giant framework structure, a main framework column adopts a high-elasticity and high-intensity structural member; a connection beam adopts a replaceable structural member, and part of a sub structure is selected as the vibration absorption sub structure; the vibration absorption sub structure comprises a vibration absorption sub structure column, a vibration absorption sub structure beam, vibration absorption sub structure additional columns, vibration isolation supports and an energy-consumption damper; the vibration absorption sub structure additional columns are respectively arranged at two ends of the vibration absorption sub structure beam; the vibration absorption sub structure column and the vibration absorption sub structure additional columns are separated from the main frame beam; the vibration absorption sub structure beam is separated from the main framework beam; the vibration isolation supports are arranged at the bottoms of the vibration absorption sub structure column and the vibration absorption sub structure additional columns; and the energy-consumption damper is arranged between the vibration absorption sub structure beam on the top and the main framework column, so that the vibration absorption sub structure is prevented from colliding with the main framework structure. The vibration absorption sub structure can absorb vibration and guide the structure to damage the vibration isolation supports, the energy-consumption damper and the connection beam, so that the function of the giant framework structure is recoverable.

Description

technical field [0001] The invention belongs to the technical field of vibration damping control, and in particular relates to a function-restorable giant frame structure including a vibration damping substructure. Background technique [0002] my country is located at the intersection of the world's two major seismic belts—the circum-Pacific seismic belt and the Eurasian seismic belt, and is one of the countries with the most severe earthquake disasters in the world. Nearly 2 / 3 of the large cities are located in areas with a basic intensity of 7 degrees or above. There has never been a country in the world that has built a large number of super high-rise buildings in earthquake zones like my country. Considering the reasons for the comprehensive use of super high-rise buildings, dense personnel, and long life expectancy of structures, it is not only required that they not collapse in strong earthquakes, but also hope that The structure has the ability to restore function (R...

Problems solved by technology

However, it is difficult to recover the function after the earthquake damage, because the beam and column joints of the main frame will dissipate most of the seismic energy while transmitting the seismic energy, and the sub-frame is not the main energy- Due to the failure of the main structure, the entire structure loses its bearing capacity mainly due to the failure of the columns at the beam-column joints of the main frame
