Embodiment Construction
[0035] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] Such as figure 1As shown, the post-tensioned prestressed self-centering steel frame structure of the present invention includes at least one structural unit, and each structural unit includes two steel frame columns 1, a T-shaped steel beam 2 connecting the upper ends of the two steel frame columns 1, The self-centering connecting piece 3 located on the lower side of the T-shaped steel beam 2 and connecting two steel frame columns 1, the frictional energy-dissipating part 4 located under the self-centering connecting piece 3, wherein the T-shaped steel beam 2 is connected with the self-centering Part 3 and steel frame column 1 are connected by hinges, so as to avoid plastic hinges at the beam-column joints when the structure undergoes lateral deformation; the length of the upper flange of T-shaped steel beam 2 is greater than the leng...
