Natural stone test method Part 10.Determination of Seismic Performance of Pendant Assembly Unit

1 Scope

This part of GB/T 9966 specifies the principle, test equipment, sample preparation, and test of the seismic performance test of a single stone pendant combined unit. Test procedures, test results and test reports. This section applies to the determination of the seismic performance of a single pendant combined unit of dry hanging natural stone.

2 Normative references

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article Pieces. For undated reference documents, the latest version (including all amendments) is applicable to this document.

3 Principle

By continuously loading and unloading the specified load on a single pendant combination unit, the performance of the pendant combination unit after 100,000 loading and unloading is determined. Appearance changes and hanging strength, so as to evaluate the seismic performance of a single pendant combined unit.

4 Test equipment

4.1 Testing machine. The relative error of the indicated value is ±1%, and the damage load of the sample should be within the range of 20% to 90% of the indicated value of the equipment. 4.2 Test fixture. When loaded to the maximum load, its deformation should be no more than 1mm, and the torsion should be less than 2°. 4.3 Seismic test bench. The test equipment should be composed of test platform, fixtures, force applying mechanism, control system and protection device. The test platform should contain a sliding platform, and a vibration mechanism is set on the platform to make the sample and the platform non-rigidly locked (simulating building vibration). when When the test is loaded to the maximum load, the deformation of the test platform should be no more than 1mm, and the torsion should be less than 2°. The equipment should include at least 5 test stations, and 5 stations can apply force at the same time. The force applying mechanism can intermittently provide.200N±2N horizontal or vertical tension and pressure to the pendant assembly unit; seismic test The force application speed of each station of the machine should be 50mm/s~500mm/s, and the stroke tolerance within the working range should not be greater than 1.0mm. The test equipment should be able to set and display test data such as vibration frequency, number of vibrations, and vibration force. 4.4 Rubber pad. meet the requirements of GB/T 5574, with a hardness of H5 or H6. 4.5 Vernier caliper. accurate to 0.1mm.

5 Sample preparation

5.1 The length of the stone sample is 300mm±1.0mm, the width is 300mm±1.0mm, and the thickness is the actual thickness; the stone sample should not have ......
