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 horizontal load, 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.

The construction method of the combined shear structure comprises the following steps:
1. all steel structural members and connecting pieces are processed in a factory in advance.
