The steel structure support hanger is a passive support made of steel, and has the advantages of high strength, good toughness, firm support, repeated use, environmental protection, convenient construction, small maintenance amount and the like. However, practice proves that various existing supports and hangers at home and abroad generally have a defect that the stability of the supports and hangers is poor when a disaster occurs. For example, although the frame structure house designed according to the new specification does not collapse much in the osaka earthquake of 1995, serious secondary disasters cause a serious disaster, and serious economic loss is caused because a water supply system is damaged and traffic life lines are paralyzed and cannot be rescued. The few major earthquakes that occurred in the 21 st century enabled the feature of little house collapse but significant economic loss to be more evident.
