The seismic support hanger cyclic loading testing machine is a key equipment used to test the seismic support performance of building electromechanical facilities. It mainly conducts load, cyclic loading, and fatigue performance tests on support hangers according to standards such as GB/T 37267-2018 and CJ/T 476-2015.
Core testing standards
GB/T 37267 "General Technical Conditions for Seismic Supports and Hangers in Buildings"
CJ/T 476 General Technical Conditions for Seismic Supports and Hangers of Building Mechanical and Electrical Equipment
According to these standards, typical testing items that the testing machine can complete include:
Component load performance: Verify the bearing capacity of seismic connection components under rated load and 1.5 times rated load.
Cyclic loading performance: At a frequency of 0.1Hz, perform 15 identical load loads first, followed by no less than 35 incremental load loads, with a displacement not exceeding 50mm.
Fatigue performance: The component should undergo 2 million fatigue tests, and after the test, there should be no cracks, obvious deformation, or detachment.
