【正文】 onsiderable force , the steel structure is smaller . this is external reason .steel frame structure have high strength steel materials , ductile materials, energy consumption is fast , yield steps is benefit to energy consumption . But Concrete structureis a brittle material.Steel structure with the minimum of steel Q235, most of the steel materials used are of Q345 . The steel structure of the damping ratio is generally between , the damping of reinforced concrete structures than the average between . The damping ratio smaller, the seismic force have large deformation , the steel toughness is good, the seismic energy consumption by deformation , so easy to restore . The steel structure is relatively soft 。Two structures in the same loads，The steel structure along the 1,2,3 axis displacement is：、 mm、15746 mm。that is reason.
