In order to detect the lateral force of the modular assembled steel structure system according to the present embodiment, the building structure formed by the steel structure modules according to the present utility model is referred to as a first building structure, and the building structure formed by the steel structure modules according to the present utility model is referred to as a second building structure, for convenience of description, compared with the building structure formed by the existing steel structure modules under the same conditions. The second building structure is a 17-layer modularized steel structure positioned at 8-degree earthquake fortification intensity. Meanwhile, the X direction and the Y direction of the building structure are directions indicated by arrows.

The rigidity of the high-rise structure is ensured, and the rigidity is a macroscopic control index for the size of the cross section and the rigidity of the component.

The data acquisition shows that the interlayer displacement angle of the first building structure is 1/576, and the design requirement is met. And as shown in fig. 7 and 8, the solid line is the detection data of the first building structure, and the broken line is the detection data of the second building structure. By comparison, the first building structure is more advantageous than the second building structure in the comparison of the X-directional interlayer displacement angle, while the first building structure is more advantageous than the second building structure in the lower layer in the comparison of the Y-directional interlayer displacement angle, as shown in fig. 8.
