Description
Technical Field
The invention belongs to the technical field of steel structures, and relates to a thin-wall steel plate PEC combined shear wall structure with a PBL shear key.
Background
Steel-concrete composite shear walls have been used in very high-rise buildings in recent years for their excellent vertical load-carrying capacity and earthquake-resistant ductility. Compared with the traditional reinforced concrete shear wall, the steel plate-concrete combined shear wall has higher bearing capacity and ductility, smaller section size, and can effectively increase the practical area of the building, is a side force resistant member with wide application prospect, and can meet the design requirement of a high-rise building structure on the shear wall of high axial compression, high ductility and thin wall, so that the steel plate-concrete combined shear wall can be widely applied to super high-rise buildings.
At present, steel plate-concrete composite shear walls applied in engineering mainly comprise an embedded steel plate-concrete shear wall, a single-side steel plate-concrete shear wall and a double-steel plate-concrete shear wall. Traditional steel plate shear walls are generally embedded with steel plates and are welded with studs, so that the steel plates and concrete work cooperatively, and meanwhile, transverse and longitudinal tie bars are arranged at two ends close to flanges, so that the local integrity of the component is improved. The embedded steel plate-concrete shear wall is seriously damaged under the working condition of large deformation, and the structural performance is limited under the action of large earthquake; because the external arrangement of the double steel plates and the concrete combined shear wall steel plates limits the high-temperature fire resistance of the structure, the structure can only be used for special buildings and is rarely applied to civil buildings. Then, an assembled-concrete combined shear wall with concrete covered by embedded steel plates, external flat steel and plain concrete components is provided, and the dead weight of the structure with the flat steel on the structural web plate greatly increased is not suitable for future higher-rise buildings.
