Title:
DOUBLE STEEL PLATE COMPOSITE SHEAR WALL HAVING EXTERNAL PRESSURE-BEARING AND UNTENSIONED CONCRETE EMBEDDED DAMPING INTERLAYER
Document Type and Number:
WIPO Patent Application WO/2020/114031
Kind Code:
A1
Abstract:
The present invention relates to the technical field of construction, and relates to a double steel plate composite shear wall that has an external pressure-bearing and untensioned concrete embedded damping interlayer. The present invention successively comprises from the inside to the outside: a concrete core layer, a steel plate layer, a damping interlayer, and an outer concrete layer. Two sides of the steel plate layer are each connected to a concrete-filled steel tube bundle, and a concrete core is poured between the steel plate layer and the concrete-filled steel tube bundles. The double steel plate composite shear wall that has the external pressure-bearing and untensioned concrete embedded damping interlayer further comprises a top plate and a bottom plate which are connected to top and bottom parts of a wall respectively. In the present invention, the outer concrete layer is not directly connected to the concrete-filled steel tube bundles at the two sides, and there are small cross-sectional areas at the top and bottom parts, so that the outer concrete layer does not directly bear horizontal loads, and will not generate deformations or else generates relatively small horizontal tensile and compressive deformations; and thus, the outer concrete layer only bears vertical loads, which greatly improves the vertical bearing capacity and seismic performance of the wall.
