Embodiment 1
[0029] Embodiment one: if figure 2 Shown in a-2b: a composite steel plate shear wall, which includes a double-layer first steel plate (2-4), a double-layer first steel plate (2-4) and an upper beam (1-1) and a lower beam (1 -1) Connection, a viscous damping wall is set between the double-layer first steel plate (2-4); the first steel plate (2-4) is not connected with the concrete column, the purpose is to reduce the impact on the column, so as to facilitate " Strong column and weak beam", the first double-layer steel plate (2-4) is provided with out-of-plane support by a viscous damping wall along the length direction of the beam; the viscous damping wall includes: a support box, inside the support box It is filled with a viscous damping fluid (2-7); the viscous damping fluid is semi-solid and semi-liquid at room temperature.
[0030] The support box includes: two outer second steel plates (2-2), an intermediate filling steel plate (2-3) between the outer second steel plates...
Embodiment 2
[0037] Embodiment two, such as Figure 5 As shown, three concrete columns (2-6) are set, that is, two viscous damping walls are set, and the first steel plate is also set in two sections along the length direction of the beam. Embodiment 2 is mainly applicable to the case where the beam length direction is long. Similarly, more than 3 concrete columns can also be set, and the first steel plate is fixed between every two concrete columns.
Embodiment 3
[0038] Embodiment 3, although Embodiment 1 solves the structure of the viscous damping wall as the external support of the steel plate shear wall, it still has two defects: one is the gap between the column (2-6) and the second steel plate (gap>interstory displacement angle under earthquake action×height of the second steel plate, the interstory displacement angle can be calculated by software such as PKPM), the first steel plate has no support at this gap; the second is the two second top horizontal plates (2-10) The inner filling steel plate must be disconnected, and the supporting effect formed by it and the second steel plate is not good. For the first question, in actual engineering, the interstory displacement angle is generally only 1 / 600, and when the wall height is 6m, the gap width is only 1cm. So this issue has less impact.
[0039] In order to solve the second problem, the content of embodiment three is as follows: divide the inner filling steel plate (2-3) in the...
