Therefore, the steel consumption is large, the steel plate shear wall belongs to a steel plate shear wall with high steel content (the steel content is not less than 4 percent), the manufacturing cost is overhigh, and the engineering cost is increased.
(3) In the existing engineering, the steel plate-concrete shear wall only exists as a structural member, a steel plate-concrete shear wall structural system is not adopted in a whole building, and a steel plate shear wall structural form is not adopted in an assembly type concrete shear wall structural system.
(4) The built-in single steel plate-concrete shear wall is formed by combining concrete and steel plates, in order to guarantee the stability of the built-in steel plates, the mode of full distribution of studs is generally adopted to guarantee the joint work of the concrete and the steel plates, but reinforcing steel bars and studs are densely arranged, the structure is complex, the construction difficulty is high, the construction cost is high, and the steel plates and the studs are only adopted in a complex structure and a super high-rise structure, so that the existing steel plate-concrete combined assembly type shear wall structure system is complex in construction, low in assembly rate and not wide in application range.
