A Confined Steel Plate Shear Wall with Easy Sliding Pressed Steel Plate Concrete

Abstract

The invention discloses a slidable profiled steel plate concrete constraint steel plate shear wall, and belongs to the technical field of buildings. The shear wall comprises steel girders, steel columns, a filler steel plate and slidable profiled steel plate concrete constraint plates. The upper side and the lower side of the filler steel plate are fixedly connected with the steel girders respectively. The left side and the right side of the filler steel plate are fixedly connected with the steel columns respectively. The front face and the rear face of the filler steel plate are provided with the slidable profiled steel plate concrete constraint plates respectively. The shear wall has large vertical rigidity and horizontal rigidity, the anti-seismic property of the steel plate shear wall is improved, the steel plate shear plate and an energy consumer are integrated, and the shear wall is widely applied to energy consumption and shock absorption of a steel structure and a reinforced concrete structure; the slidable profiled steel plate concrete constraint plates can slide horizontally, and profiled steel plate ribs are disengaged from connecting mortar under large loads and can be freely stretched out and drawn back; the friction force between profiled steel plates and embedded steel plates is small, and the profiled steel plates and the embedded steel plate can slide relatively and freely; high energy consumption is achieved, and the shear wall is an excellent anti-seismic energy consumption component.

my country is located in the two most active seismic belts in the world, and is one of the countries that suffered the most severe earthquake disasters. The casualties caused by the earthquake rank first in the world, and the economic loss is also very huge; a large number of buildings were destroyed and collapsed during the earthquake, It is the direct cause of earthquake disasters; when an earthquake occurs, the ground vibration causes the seismic response of the structure; for a building structure whose foundation is fixed on the ground, its response is amplified layer by layer along the height from bottom to top; due to a certain part of the structure The earthquake response (acceleration, velocity or displacement) is too large, causing serious damage or even collapse of the main load-bearing structure; or although the main structure is not damaged, the building decoration, decoration or other non-structural accessories are damaged, resulting in serious losses; or indoor expensive equipment , Equipment damage leads to serious losses or secondary disasters; in order to avoid the occurrence of the above disasters, people must control the seismic response of the structural system and eliminate the "amplifier" effect of the structural system

[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 structural system is difficult to realize, and it is not economical. Only a very small number of important buildings adopt this structural system; with the development of society, buildings are becoming more and more Huge and complex, people have higher requirements for the safety of buildings, so it is more difficult to achieve the expected fortification goals within a reasonable economic range, people are faced with a dilemma between safety and economy; secondly, People do not know enough about earthquakes, and there is still a certain distance between the predicted seismic response of structures and the actual seismic response, so the anti-seismic measures taken are not completely reasonable.

[0006] The energy-dissipating steel plate wall currently researched and developed has Chinese patent number 200810034557.1, which discloses an invention patent named "High-rise vertical shear energy-dissipating steel plate wall structure system"; this structure is difficult to slide relative to the horizontal force-resistant system and the steel plate wall. It will cause the force in the plane to increase sharply, so that the horizontal lateral force system cannot achieve the effect of constrained buckling outside the plane; in addition, because the horizontal lateral force system is often due to the large out-of-plane In addition, due to the extremely poor tensile properties of concrete, it often causes premature cracks in the concrete of the horizontal lateral force system, and loses the restraining effect outside the plane, so that the advantages of the structure cannot be exerted, and the energy consumption capacity is significant. reduce

[0007] 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. These problems need to be better resolved
