[0002] Seismic bracing for water pipes consists of various components or devices that limit the displacement of water pipe facilities, control the vibration of the facilities, and transfer the load to the load-bearing structure. During an earthquake, the building structure is subjected to seismic forces, and the toughness of the seismic bracing for water pipes is directly related to its stress-bearing capacity during an earthquake. By testing the toughness, the deformation capacity and load-bearing capacity of the bracing under seismic loads can be assessed, thereby ensuring that the water pipe system does not suffer serious damage or failure during an earthquake. In the existing technology, the toughness of the seismic bracing for water pipes is usually tested by directly compressing it.

The bottom of the first limiting plate 265 and the second limiting plate 267 are provided with anti-slip texture.

Then, the third hydraulic cylinder 31 supports the extrusion head 33 to press down. The upper end of the extrusion head 33 contacts the pressure sensor. The water pipe seismic bracing after the extrusion head 33 is pressed down and limited is subjected to toughness testing.
