Embodiment 1
[0023] Such as figure 1 As shown, the loading device for the out-of-plane deformation fatigue test of the web gap between the vertical stiffener and the wing plate of this embodiment is composed of a servo hydraulic actuator 1, a loading beam 2, a connection assembly 3, a ground anchor 4, and a concrete leveling layer 6 composition.
[0024] The loading beam 2 of this embodiment is an I-shaped beam welded from steel plates, see figure 2 The upper flange plate 2-1 is a rectangular steel plate with a width of 400mm, a thickness of 40mm, and a length of 1000mm. The load beam web 2-2 is a rectangular steel plate with a width of 200mm, a thickness of 20mm, and a length of 1000mm. The lower wing The edge plate 2-3 is a rectangular steel plate with a width of 400mm, a thickness of 40mm, and a length of 1000mm. In order to temporarily fix the loading beam 2 on the reaction frame, the left and right ends of the upper flange 2-1 of the loading beam 2 are welded with loops 2-4 made of thic...
Embodiment 2
[0033] The upper flange plate 2-1 of the loading beam 2 in this embodiment is a rectangular steel plate with a width of 250 mm, a thickness of 16 mm, and a length of 500 mm. The load beam web 2-2 is a width of 100 mm, a thickness of 12 mm, and a length of 500 mm. For rectangular steel plates, the geometry and size of the lower flange plate 2-3 and the upper flange plate 2-1 are the same.
[0034] The horizontal top plate of the steel anchor box 4-1 of this embodiment is a rectangular plate with a width of 250 mm, a thickness of 18 mm, and a length of 300 mm, and the vertical wing plate is a rectangular plate with a width of 150 mm, a thickness of 16 mmm, and a length of 400 mm.
[0035] The other components and their connection relationship are the same as in the first embodiment.
Embodiment 3
[0037] The upper flange plate 2-1 of the loading beam 2 of this embodiment is a rectangular steel plate with a width of 550mm, a thickness of 60mm and a length of 1500mm. The web 2-2 of the loading beam is a width of 500mm, a thickness of 24mm, and a length of 1500mm. For rectangular steel plates, the geometry and size of the lower flange plate 2-3 and the upper flange plate 2-1 are the same.
[0038] The horizontal top plate of the steel anchor box 4-1 of this embodiment is a rectangular plate with a width of 400 mm, a thickness of 24 mm, and a length of 800 mm, and the vertical wing plate is a rectangular plate with a width of 450 mm, a thickness of 22 mmm, and a length of 600 mm.
[0039] The other components and their connection relationship are the same as in the first embodiment.
