The traditional support bracket system is a support system with gravity as the main load. The traditional gravity supports and hangers only bear the vertical load, which have large lateral swing and may damage the adjacent facilities or even fall off. And the horizontal earthquake action lacks the support structure.
The seismic support and hanger mainly bear the horizontal load of the pipeline. Arranging the seismic support and hanger could change the dynamic characteristics of the pipeline system from flexible to rigid, so as to significantly reduce the response to the earthquake. Changing the stress of the gravity hanger could change the design, type selection, stiffening and anchoring. The anti-seismic support and hanger are divided into vertical and horizontal supports and hangers. The stress, layout and anchoring are related to the multidisciplinary and multifield knowledge, including earthquake engineering, structural engineering, mechanical engineering, water supply and drainage and etc.
