1. The floor should be cast-in-place reinforced concrete composite floor or non composite floor with profiled steel sheet.
2. The layout of the supporting frame in both directions should be basically symmetrical, and the length width ratio of the floor between the supporting frames should not be greater than 3;
3. When the steel structure building is equipped with basement, the frame column should extend to the basement at least;
4. When the steel structure with more than 12 stories adopts eccentrically braced frame, the top floor can adopt central support;
5. For steel frame tube structure with more than 12 stories, if necessary, a strengthening layer composed of outrigger or outrigger and surrounding frame can be set;
We all know that once an earthquake occurs, it will cause unpredictable damage to life and property, so when we do steel structure construction, we should have a clear understanding of the seismic layout requirements of steel structure, and do enough preventive work, so as to minimize the impact of earthquake.
