Double-layer weakened fabricated steel plate shear wall structure

Abstract

The invention discloses a double-layer weakened fabricated steel plate shear wall structure. The double-layer weakened fabricated steel plate shear wall structure comprises a frame system, a front-side crease steel plate and a reverse-side crease steel plate. The front-side crease steel plate is fixed on the front side of the frame system. First-class creases are arranged on the front-side creasesteel plate. The reverse-side crease steel plate is fixed on the reverse side of the frame system. Second-class creases are arranged on the reverse-side crease steel plate. The first-class creases arecomposed of inclined creases and horizontal creases which have a first inclination angle, and the inclined creases and the horizontal creases are arranged at equal intervals. The second-class creasesare formed by inclined creases with a second inclination angle. The inclined creases of the second-class creases are also arranged at equal intervals. The orthographic projections of the inclined creases of the second-class creases penetrate through the intersection points of the inclined creases and the horizontal creases in the first-class creases. According to the double-layer weakened fabricated steel plate shear wall structure, a crease steel plate shear wall can yield according to a specified form, has better lateral stiffness and bearing capacity, better energy consumption characteristic and better ductility, and is an efficient anti-seismic, shock-absorbing and energy-dissipating component.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, in particular to an assembled folded steel plate shear wall with four sides connected based on the origami principle. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, my country has made great progress in high-rise and super high-rise buildings. In high-rise and super high-rise buildings, steel plate shear wall structures are often used. Steel plate shear walls are often used as the main lateral force-resisting members in high-rise and super high-rise buildings, and play a vital role. When the earthquake acts, the steel plate shear wall often bears its main function, plays the role of anti-seismic energy consumption, and ensures the safety and stability of the building structure. With the increase of earthquake action, the structural part of the steel plate shear wall structure is prone t...

Problems solved by technology

However, the current technology needs to use external components to reinforce the steel plate shear wall, which makes the structure more complex and difficult to mass-produce in chemical factories. Improvements such as opening holes and slits on the steel plate will also significantly weaken the steel plate shear wall Ultimate load carrying capacity and lateral stiffness
