Detailed Description
The invention is further illustrated by the following figures and examples.
Example 1:
the multi-cavity steel plate built-in steel tube high-strength concrete shear wall shown in fig. 1-3 comprises an outer steel plate 1, a partition plate 3 and a steel tube 2; the steel pipe 2 is respectively arranged in each cavity, and concrete is poured into the cavities and the steel pipe 2. The steel pipe 2 is a hollow round steel pipe, and the steel plates 1 are connected by welding to form a space with a closed cross section (namely, the periphery is closed). Inside ordinary concrete 5 intussuseption in outsourcing steel form, the steel sheet retrains each other with the concrete, and collaborative work fills ordinary concrete 5 and can play the constraining action to outsourcing steel sheet 1 in outsourcing steel sheet 1 is inside, can effectively restrain the steel sheet buckling, and outsourcing steel sheet 1 has the constraining action to inside ordinary concrete 5 equally moreover to improve the deformability of intussuseption ordinary concrete 5, prevent that ordinary concrete 5 from ftractureing and peeling off. The thickness of the outer steel plate 1 and the steel pipe 2 is not less than 10mm, the steel content of the section is preferably within the range of 0.04-0.2, and the hoop coefficient of the steel pipe is preferably between 0.5-2.0. When the center position of each cavity is provided with a steel pipe, the bearing capacity of the shear wall is optimal.
The partition plates 3 are arranged at intervals along the length direction of the shear wall, two ends of each partition plate 3 are respectively connected with two oppositely-arranged outer-wrapped steel plates 1 to divide the space into a plurality of cavities, and at least one steel pipe 2 is arranged in each cavity. A plurality of partition plates 3 are arranged along the length direction of the shear wall, the partition plates 3 are welded between steel plates wrapped on two sides of the shear wall, and the steel plates on two sides of the shear wall are divided into cavities which are relatively independent. Through the arrangement, the bearing capacity and the ductility of the shear wall are improved, and the shear wall is effectively prevented from being bent and unstable integrally under high axial force and horizontal force. When the steel tube is used specifically, a plurality of steel tubes can be uniformly distributed in the cavity. The steel pipe 2 is arranged along the height direction of the shear wall, and the steel pipe and the shear wall are equal in height. In the embodiment, the preferable scheme is that only one steel pipe is arranged at the center of the cavity, and the bearing capacity, the ductility and the energy consumption performance of the shear wall are optimal.
The shear wall further comprises stiffening ribs 4, wherein the stiffening ribs 4 are uniformly distributed on the inner walls of the two oppositely-arranged steel plate outsourcing 1 plates along the length direction of the shear wall, and a space is formed between the stiffening ribs 4 on the two steel plate outsourcing 1 plates. The inner surface welding of outsourcing steel sheet 1 has a plurality of stiffening ribs 4, can prevent effectively that this shear force wall from taking place local buckling under high axial pressure, strengthens the bonding of outsourcing steel sheet and concrete simultaneously, effectively improves the bearing capacity and the deformability of shear force wall.
As shown in fig. 4, the steel pipe frame further comprises a plurality of shear ring ribs 7, wherein the shear ring ribs 7 are uniformly arranged on the outer circumferential wall of the steel pipe 2 along the length direction of the steel pipe 2. The outer surface of the steel pipe 2 is welded with a plurality of shear ring ribs 7, so that the adhesive coupling between the steel pipe 2 and the common concrete 5 is enhanced, the outer surface of the steel pipe 2 is tightly combined with the common concrete 5, and the surface shear bearing capacity of the steel pipe is enhanced. The common concrete always provides lateral constraint force for the built-in concrete filled steel tube, the problem of out-of-plane instability of the concrete filled steel tube under high axial pressure and horizontal force can be effectively prevented, and the performance of the concrete filled steel tube is fully exerted.
When the shear wall is used specifically, the plurality of wrapping steel plates 1 are welded into closed figures with different cross sections, so that the shear wall is in different shapes. Such as: the outer steel plates 1 are connected to enclose a rectangle with a closed cross section, so that the shear wall is in a straight shape. And a plurality of the steel plate covers 1 are connected and enclosed into an L shape with a closed cross section, so that the shear wall is in an L shape. And a plurality of the steel plate wrapping layers 1 are connected and enclosed into an I-shaped structure with a closed cross section, so that the shear wall is in an I shape. And a plurality of the steel plate wrapping layers 1 are connected to enclose a T-shaped structure with a closed cross section, so that the shear wall is in a T shape.
As shown in fig. 5 and 6, the multi-cavity steel plate built-in steel tube high-strength concrete shear wall has various arrangement forms, and can be arranged in a straight line shape, an L shape, a T shape, an i shape and the like.
As can be seen from the side load-displacement curve shown in fig. 7, the shear wall has a relatively large initial side stiffness, and after the shear wall enters the plastic stage, the side resistance of the shear wall is still continuously improved without reduction along with the increase of horizontal displacement; as can be seen from the vertical load-displacement curve shown in fig. 8, the shear wall has higher axial compression stiffness, and after the shear wall enters the plasticity stage, the load-bearing capacity of the shear wall first decreases with the increase of the vertical displacement, but the decrease range is not large, and then the load-bearing capacity is basically maintained at a certain value and remains unchanged. Therefore, the multi-cavity steel plate built-in steel pipe high-strength concrete shear wall still has higher bearing capacity and ductility no matter bearing horizontal load or vertical load, and meets the requirements of the super high-rise building on high bearing capacity, high ductility and high energy consumption of the shear wall.

the present example is the same as example 1 except for the following technical features:
the partition plates 3 are arranged at intervals along the width direction of the shear wall, two ends of each partition plate 3 are respectively connected with two oppositely-arranged outer-wrapped steel plates 1 to divide the space into a plurality of cavities, and at least one steel pipe 2 is arranged in each cavity. The partition plate 3 can be arranged along the length direction or the width direction of the shear wall under the condition of meeting the use requirement. When the partition plate 3 is arranged along the width direction of the shear wall, the steel pipe 2 can be arranged along the vertical direction, and the steel pipe 2 and the shear wall are equal in height at the moment, or the steel pipe 2 can be arranged along the horizontal direction, and the steel pipe 2 and the shear wall are equal in length at the moment.
