The h ighest point of the wheel is 208m above ground level, and its diam eter is 198m. It is the b igge st ferris wheel in the world. The general situation, the structu ral system , the load ca ses and their comb in ition of the wheel are p re sented in the p ap er. A 3D num erical model was bu ilt. Fin ite elem en t software M IDA S was adop ted for the design check and analysis of the structure. The re su lts show that the de sign of the structu re satisfie s the national codes. The vibration mode s and frequencies of the structure were obtained by the dynam ic analysis. The reliab le data were p rovided for the further design.
