Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, in particular to a shear wall performance testing device. Background Art

[0002] The material of shear wall is generally reinforced concrete wall, which is mainly used to bear horizontal loads, such as wind loads or earthquakes. The advantages of shear wall structure are large lateral stiffness and small lateral displacement under horizontal loads. Generally, flat plates are used and beams are not required, so space utilization is better and floor height can be saved.

[0003] According to the use characteristics of the shear wall, its performance needs to be tested before it can be put into use. When an earthquake occurs, the earth's crust shakes back and forth, so the force applied to the shear wall should be uneven. It is difficult to grasp the force applied by directly using methods such as knocking. When testing the shear wall, a reaction force will be generated while applying pressure to the shear wall, which can easily make the position of the device unstable. For this reason, we propose a shear wall performance test device. Utility Model Content
