Background
Compared with a reinforced concrete shear wall, the double-steel-plate-concrete combined shear wall has the advantages of high rigidity, high bearing capacity, high energy consumption capacity and the like, has good ductility and energy consumption capacity under large interlayer displacement, and can be matched with a steel column or a combined column with good energy consumption capacity; the thickness of the combined shear wall is obviously smaller than that of a reinforced concrete shear wall, the dead weight of the structure can be effectively reduced, the foundation burden is reduced, the using area of the building is increased, the economic benefit is improved, and the combined shear wall is easy to repair after an earthquake.
Although the performance and the strength of the existing steel plate shear wall can meet the use requirements, when the outer steel plate is thin, the outer rigidity of the steel plate is poor, a tension band can be generated after the steel plate is bent under the reciprocating action of wind and earthquake, the outer bulging and bending of the steel plate wall can be alternated, the rigidity of the bearing capacity can be sharply reduced in the alternation process, and the pinching phenomenon of a hysteresis curve is caused; moreover, because the external rigidity of the steel plate surface is poor, the deformation and the stability of the steel plate shear wall member processed in a factory are poor in the transportation and field hoisting processes, a large number of temporary reinforcing members need to be added, and the transportation and installation efficiency is greatly reduced.
