Abstract：Base on a case study of 208-meter-high Ferris wheel under construction, both dynamic characteristic and seismic behavior were studied with ANSYS. Firstly the natural vibration characteristics of various structure parameters were studied. The numerical results indicated that basic frequency was on the small side and frequency spectrum was concentrated. Main mode shape of vibration was rim’s vibration itself because stiffness of rim structure was small. Then the responses of the structure under frequent earthquake were analyzed using both the response spectrum method and time-history method respectively. Structural deformation met the requirements of Chinese code for seismic design of buildings. Stress of whole structure’s members was small and met the requirement of no-damage under frequent earthquake. Finally the responses of the structure under rare earthquake were studied using the dynamic elastic-plastic time-history method. The numerical results demonstrated that the inelastic deformation met the requirements of Chinese code for seismic design of buildings and no-collapse under rare earthquake.
