At present, steel structures are paying more and more attention to earthquake-resistant skills. Discovering the characteristics of earthquake damage between steel structures helps steel structures to better prevent earthquakes. Finding characteristics in the damaged areas of steel structures can be used instead of preparations. Severe natural disasters (such as earthquakes, a series of disasters caused by earthquakes) will reduce casualties.
The general situation of steel structure engineering damage, due to insufficient component strength, component instability, reasonable configuration of the support system to ensure the overall stability of the site structure, is particularly important for the steel structure site. The overall configuration requires that the quality and rigidity of the on-site structure be uniformly distributed, so that the on-site force is uniform and the deformation is coordinated, and the uneven rigidity of the structure should be prevented from causing adverse effects on earthquake resistance.
The central support structure of seismic fortification should choose cross-interspersed oblique rod, single oblique rod herringbone oblique rod or V-shaped oblique rod system, and K-shaped oblique rod system shall not be selected. When selecting a single-inclined rod system that can only be stretched, two sets of single-inclined rods with different inclination directions should be set, and the difference in the horizontal projection area of the cross-sectional area of the single-inclined rods in different directions in each layer shall not exceed 10%.
