First, the traditional bearing support system is the support system with gravity as the main load (the traditional gravity supporting frame only takes the vertical load);
1, lateral sway, destruction of adjacent facilities, or even fall off;
2, horizontal earthquake action lacks support structure;
Two 、 the anti-seismic support mainly bears the load in the horizontal direction of the pipeline;
1. Laying down seismic hangers and hangers to change the dynamic characteristics of the pipeline system, and the response is changed slightly under the action of the earthquake;
2. Change the force of the gravity hanger at the seismic support hanger, and then change the design, type selection, stiffening, anchorage and so on;
3 、 seismic support hangers are divided into longitudinal and transverse hangers, and their stress, layout and anchorage involve multidisciplinary and multi field knowledge of earthquake engineering, structural engineering, mechanical engineering, water supply and drainage.
