Cross reinforced steel plate buckling-preventing energy dissipation wall

Abstract

The invention provides a cross reinforced steel plate buckling-preventing energy dissipation wall which mainly comprises a cross reinforced steel plate, an infilling steel plate, a bolt, a nut, a steel base plate, a steel column, a steel beam, an angle plate, a base plate, a screw hole and the like. The cross reinforced steel plate buckling-preventing energy dissipation wall is characterized in that the cross reinforced steel plate is in a cross shape and is respectively cut by four parabolic curves, and relative wider areas are formed on the cross points and in the four corners of the cross reinforced steel plate; and the cross reinforced steel plate is arranged at one side or both sides of the infilling steel plate. The cross reinforced steel plate buckling-preventing energy dissipation wall provided by the invention has the advantages of being higher in vertical rigidity and horizontal rigidity, improving the anti-seismic property of a steel plate shear wall, realizing that the steel plate shear wall and an energy dissipater are integrated into an integer and being widely used for the energy dissipation and vibration reduction of a steel structure and a reinforced concrete structure, has a series of superior characteristics of high bearing capacity, high lateral-resistant rigidity, high energy-dissipating capacity, and the like under seismic action and is a superior anti-seismic energy-dissipating component.

Description

technical field [0001] The invention relates to an energy-dissipating steel plate wall of a building structure, in particular to a buckling-resistant energy-dissipating wall of cross-reinforced steel plates for a building structure. Background technique [0002] Earthquake disasters are sudden and devastating, which seriously threaten the safety of human life and property. Nearly a thousand destructive earthquakes occur every year in the world, and a major earthquake can cause hundreds of billions of dollars in economic losses, resulting in hundreds of thousands of deaths or serious injuries. my country is located in the two most active seismic belts in the world, and is one of the countries that suffered the most serious earthquake disasters. The casualties caused by the earthquake rank first in the world, and the economic loss is also very huge. The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. When an earthquak...

Problems solved by technology

[0003] At the beginning of the 20th century, the calculation method proposed by Professor Omori Fangyoshi and the seismic coefficient method proposed by Dr. Sano Toshiki did not consider the dynamic characteristics of the structure. Later, people called it the static theory of seismic design. In order to resist earthquakes, they tended to use Rigid building structure, that is, "rigid structural system", but this kind of structural system is difficult to realize, and it is not economical. Only a very small number of important buildings adopt this structural system

[0006] However, at present, some energy-dissipating steel plate walls are prone to buckling, and some energy-dissipating steel plate walls have relatively concentrated plastic distribution, which is not conducive to energy consumption, and they all need to be better resolved.
