Inner energy consumption inner core (24) is yi word pattern single steel plate, is circular arc; Inner energy consumption inner core (24) one end is two vertical junction plates with it: inner energy consumption inner core upper junction plate (26), inner energy consumption inner core lower connecting plate (26), be connected with energy consumption inner core (24) vertical welding; Supporting member end junction plate (27) is upper with bolt hole, by high-strength bolt and framework, is linked together; Inner energy consumption inner core upper junction plate (26), lower connecting plate (27) are welded together by short stiffener (28); Short stiffener (28) is all vertical with (27) junction plate under (26) in inner energy consumption inner core; Spring stripper plate (25) is used for retraining support column (22), and carrys out Compress Spring (29) with the twitch of energy consumption inner core;
Peripheral channel-section steel confining part (24) is two relative channel-section steels, channel-section steel outward opening, a segment distance is left in centre, this distance is the thickness of inner energy consumption inner core (24), so that energy consumption inner core penetrates in the middle of two channel-section steels, channel-section steel respectively welds a frange plate up and down, i.e. external frame confining part top flange plate (17) external frame confining part bottom wing listrium (18), fixing channel-section steel, and together as the peripheral constraint component of supporting member; Upper and lower frange plate two ends are longer than channel-section steel;
In the prestressed member of structure Self-resetting prestressing force supporting member, prestressed cable (30) is arranged symmetrically in the both sides of energy consumption inner core (24); Through the transverse stiffener (20) in the middle of external frame confining part channel-section steel, its two ends are connected with the upper junction plate (26) of inner energy consumption inner core fine strain of millet end respectively, and tie point is positioned at two adjacent short stiffener (28) district centers of a lattice.
