FEM Analysis on a New Type of Anti-Tension Device

A new type of anti-tension device was put forward. One specimen on three utlimate working conditions was analyzed by FEM. The research results showed that there was large eccentricity between the upper steel frame and the lower steel frame in the horizontal plane, the maximum bearing capacity of the device would decrease to some extent, especially in two direction eccentricity condition. In the Sap2000 program, the characteristic of the device met with that of Hook element, some parameters of the model had been identified. Hook element could model this device when it was on the elastic stage.
