Among them, the second building structure is a 17-story modular steel structure located at the seismic fortification intensity of 8 degrees. At the same time, the X and Y directions of the above-mentioned building structure are the directions indicated by the arrows.

In this embodiment, the comparison is the interstory displacement angle of the first building structure and the second building structure, and the interstory displacement angle refers to the maximum interstory displacement under the wind load calculated by the elastic method or the standard value of frequent earthquakes.

It can be seen from the comparison that in the comparison of the X-direction story displacement angle, the first building structure is superior to the second building structure, and as shown in Figure 8, in the comparison of the Y-direction story displacement angle, in the lower layer , the first building structure is superior to the second building structure. And as the height of the floor increases, the displacement angle between the first building structure and the second building structure tends to be the same in the Y direction.
