technical field

The utility model belongs to the technical field of building materials, in particular to a profiled steel plate concrete reinforced steel plate energy dissipation wall.

Background technique

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 earthquake occurs, ground vibrations cause the seismic response of the structure. For a building structure whose foundation is fixed to the ground, its response is amplified layer by layer along the height from bottom to top. Due to the excessive seismic response (acceleration, velocity or displacement) of a certain part of the structure, the main load-bearing structure is seriously damaged or even collapsed; loss; or damage to indoor expensive instruments and equipment leading to serious losses or secondary disasters. In order to avoid the occurrence of the above-mentioned disasters, people must control the seismic response of the structural system and eliminate the "amplifier" effect of the structural system.

The steel plate shear wall structure is a new type of lateral force-resisting structural system developed in the 1970s. The steel plate shear wall is composed of embedded steel plates, vertical edge members (columns), and horizontal edge members (beams). , the embedded steel plate is equivalent to the beam web, and the horizontal edge member can be approximately equivalent to the transverse stiffener. Embedded steel plates can be constructed without stiffeners or with stiffeners. Steel plate shear walls without stiffeners can make full use of the post-buckling strength of steel plates under strong earthquakes, and have good ductility and energy dissipation capacity. The stiffened steel plate shear wall can limit the out-of-plane buckling of the steel plate, thereby improving the buckling capacity of the structure, which helps to enhance the lateral stiffness of the structure under the action of wind and small earthquakes and facilitates construction. Compared with the traditional steel frame or steel frame plus concrete shear wall structure system, the steel plate shear wall structure has the advantages of thin thickness, light weight, fast construction speed and good ductility. The existing research results and engineering examples show that the steel plate shear wall is a lateral force resistant structural system with great development potential, especially suitable for high-rise buildings and seismic reinforcement in high-intensity earthquake fortification areas. In the past few decades, scholars from various countries have conducted many experimental and theoretical studies on this structure. These studies have all come to a common conclusion: the structure has high elastic initial stiffness, large displacement ductility coefficient, and stable hysteretic performance.

The current energy-dissipating steel plate wall researched and developed has Chinese Patent No. 200810034557.1, which discloses an invention patent named "High-rise vertical shear energy-dissipating steel plate wall structure system". This patent uses a steel plate wall as a vertical energy-dissipating component. However, due to the lack of lateral constraints of the steel plate wall, the steel plate wall is prone to buckling, and the energy dissipation effect of the steel plate wall cannot be fully utilized. This patent sets lateral constraints for the steel plate wall, which effectively limits the out-of-plane buckling of the steel plate wall.

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 need to be better resolved.
