8. A method for installing an assembled double-energy-consuming resettable round steel tube concrete composite column according to any one of claims 1 to 7, comprising the steps of:
the first step is as follows: connecting the round stiffening steel pipe (8) and the constraint support (6) through a high-strength bolt;
the second step is that: fixing the splicing support (5) and the lower end steel bar through a fastener;
the third step: connecting an upper section of circular steel tube (18) with an upper sleeve connecting piece (14), and connecting a lower section of circular steel tube (20) with a lower sleeve connecting piece (15);
the fourth step: the prestressed reinforcement (21) sequentially penetrates through a reinforcement fixing plate at the upper end of the upper section of the circular steel tube (18), the circular steel tube column and a reinforcement fixing plate at the lower end of the lower section of the circular steel tube (20);
the fifth step: the energy-consuming hinged steel plate (4) is connected with the II-type column (3) through a hinged shaft (22) outside the plane of the I-type column (2) and the II-type column (3), then is turned into the plane of the I-type column (2) and the II-type column (3) by taking the hinged shaft (22) as a rotating shaft, and is connected with the stiffening hinged plate (9) through a splice plate and a high-strength bolt;
and a sixth step: the flange of the H-shaped steel beam (7) is inserted between the inserting plate (12) of the upper sleeve connecting piece (14) and the inserting plate (12) of the lower sleeve connecting piece (15), the two sides of the inserting plate (12) and the flange are overlapped through a web connecting plate (25), the upper flange of the H-shaped steel beam (7) is overlapped with the end plate (11) of the upper sleeve connecting piece (14), and the lower flange of the H-shaped steel beam (7) is overlapped with the end plate (11) of the lower sleeve connecting piece (15) through a flange connecting plate (24);
the seventh step: fiber concrete is poured into the circular stiffening steel pipe (8) of the type I column (2) and the circular steel pipe (13) of the type II column (3), so that the connecting parts are fastened and connected through occlusion to form a whole.
