Example Embodiment
[0043] Example 1
[0044] A steel plate-steel support combined lateral force resistance member of this embodiment includes a steel plate 1, a steel support 2 integrated with the steel plate 1, and the shape of the steel plate 1 is a rectangle with two corners on the same side cut off, forming a " Convex" shaped structure, the shape of the cut part is square, the steel support 2 includes two symmetrical parts, and they are respectively placed on both sides of the steel plate 1. The cross-sectional shape of the steel support 2 composed of the two parts is rectangular, and the two parts of the steel support 2 Part of it is channel section steel made by cold working. There are 10 bolt holes 8 equally spaced on the steel support 2. The distance between the bolt hole 8 and the end of the steel support 2 is 150mm, and the corresponding position of the steel plate 1 is also provided with 10 bolt holes 8, two parts of the steel support 2. They are connected to the steel plate 1 through h...

[0046] Example 2
[0047] The basic structure of a steel plate-steel support combined lateral force member and beam-column structure using the member of this embodiment is the same as that of the first embodiment. The difference is that the steel support 2 includes two symmetrical parts, which are respectively placed on the steel plate On both sides of 1, the cross-sectional shape of the two-part steel support 2 is circular, the two parts of the steel support 2 are semi-circular cross-section steel obtained by splitting a circular tube, and the steel support 2 is equidistantly opened with 15 The distance between the bolt hole 8 and the end of the steel support 2 is 175mm. The corresponding position of the steel plate 1 is also provided with 15 bolt holes 8. The large diameter of the high-strength bolts and nuts is 14mm, and the distance between the high-strength bolts is 250mm. The material of steel plate 1 and steel support 2 is Q345. The thickness of the fish plate 3 is 2.5 ti...

[0048] Example 3
[0049] The basic structure of a steel plate-steel support combined lateral force resistant member and the beam-column structure using the member of this embodiment is the same as that of the first embodiment. The difference is that the steel support 2 is equidistantly provided with 20 bolt holes 8 The distance between the bolt hole 8 and the end of the steel support 2 is 200mm, and the corresponding position of the steel plate 1 is also provided with 20 bolt holes 8. The major diameter of the high-strength bolts and nuts is 14mm, and the distance between the high-strength bolts is 300mm. The material of support 2 is Q345. The thickness of the fish plate 3 is 3 times the thickness of the steel plate 1, and a corner is cut off on both the gusset plate 4 and the gusset plate stiffener 7, and the cut corner size is 40 mm.
