Research on the Mechanical Performance of New Air Duct Seismic Support Hanger
As a non-structural component,seismic support hangers have the function of ensuring the normal operation of ancillary mechanical and electrical equipment of buildings during earthquakes.In order to improve the seismic resistance of air duct seismic support hangers and reduce the amount of steel used,a new air duct seismic support hanger is proposed,which is mainly composed of screw rods,vertical C-shaped steel beam,upper and lower horizontal C-shaped steel beam,seismic connectors,limiters and steel cables.By comparing with the traditional air duct seismic support hangers,the effects of changing the height and width of air duct,the diameter of screw rods and steel cables,and upper suspension length of air duct on the mechanical performance of the traditional and new seismic support hangers are studied.The research results indicate that the mechanical performance of the new air duct seismic support hangers is superior to that of the traditional air duct seismic support hangers,and its steel consumption is slightly lower than that of the traditional air duct seismic support hangers,which has good practicality and economy.
