Inner energy consumption inner core (20) is cross biplate steel plate.Two yi word pattern steel plates are intersected vertically and welded together, form cross biplate angle steel; For making energy consumption inner core be easy to enter plasticity power consumption, weaken chip board middle part, be circular arc.Energy consumption inner core one end is two vertical junction plates with it: upper junction plate (21), lower connecting plate (22) are connected with energy consumption inner core vertical welding.Supporting member end outermost junction plate, with bolt hole, links together high-strength bolt and framework.Upper junction plate (21), lower connecting plate (22) are welded together by short stiffener.Short stiffener is all vertical with two plates.Inner core junction plate (28) is used for retraining support column (17), and carrys out Compress Spring (18) with the twitch of inner core plates;
Peripheral angle steel confining part (24) is four angle steel, and four angle steel are lined up cross, and the limb back of the body facing each other connects with bolt, between relative limb, with bolt, connects.Each bolt sleeve has sleeve pipe (25), and sleeve pipe (25) length is identical with energy consumption inner core thickness.Sleeve (25) is positioned between the bolted two limb back ofs the body.Between two limbs of each angle steel, be all connected with transverse stiffener.
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 (20); Through the transverse stiffener (26) in the middle of outside angle steel confining part, its two ends are connected with the upper junction plate (21) at inner energy consumption inner core two ends respectively, and tie point is positioned at two adjacent short stiffener (26) district centers of a lattice.
