Embodiment 2
[0044] In this embodiment, the rectangular concrete-filled steel pipe column-H-shaped steel beam trapezoidal slab connection node includes a rectangular concrete-filled steel pipe column 1, an H-shaped steel beam 2, and a composite ring-plate group 3, and the composite ring-plate group 3 includes a first composite ring-plate 31 and a composite ring-plate group 3. The second composite ring plate 32, the first composite ring plate 31 and the second composite ring plate 32 are all welded to the web of the rectangular steel pipe concrete column 1, and the first composite ring plate 31 and the second composite ring plate 32 are along the rectangular steel tube The concrete column 1 is arranged opposite to each other in the axial direction, and the first composite ring plate 31 and the second composite ring plate 32 are provided with connecting ends. The first composite ring plate 31 and the upper flange plate on the side of the H-shaped steel beam 2 Welded with the lower flange plat...
Embodiment 3
[0050] The difference from Example 2 is that the first composite ring plate 31 and the second composite ring plate 32 are the same as the steel used in the H-shaped steel beam 2 for the connection node between rectangular steel tube concrete column and H-shaped steel beam trapezoidal plate in this embodiment , namely f 1 =f 0 , when the thickness of the upper flange plate of the H-shaped steel beam 2 and the thickness of the lower flange plate of the H-shaped steel beam 2 are equal to the thickness of the first composite ring plate 31 and the thickness of the second composite ring plate 32, then the first The thickness of the composite ring plate 31 or the thickness of the second composite ring plate 32 and the size of the H-shaped steel beam 2 satisfy the formula b 1 = 3a; when the width of the upper flange plate of H-shaped steel beam 2 or the width of the lower flange plate of H-shaped steel beam 2 is 200mm, the first composite ring plate 31 and the upper flange plate of H...
