Embodiment Construction
[0014] The content of the present invention is described below in conjunction with embodiment. Such as figure 1 Shown, is the main part of the mild steel shear hysteretic damper of the present invention, namely image 3 with Figure 4 Parts shown in shaded.
[0015] The damper of the present invention comprises: a rigid connecting plate 1 , a hysteretic energy dissipation web 2 , a transverse stiffener 3 , a flange 4 and a longitudinal stiffener 5 . Among them, the hysteretic energy-dissipating web 2 is the main energy-dissipating plate, and the rigid connecting plate 1 and the flange 4 are welded around it. When there are reliable edge constraints around the hysteretic energy dissipation web 2 (such as Figure 4 example shown), such rigid connecting plates 1 and flanges 4 can be omitted. The transverse stiffener 3 and the longitudinal stiffener 5 can be welded on one side or both sides of the hysteretic energy dissipation web 2 . When the softness ratio parameters of th...
