The"Eye of Xuancheng"ferris wheel built in Xuancheng,Anhui Province,adopts a new column support system.This paper takes the ferris wheel as the research object,and makes a simulation analysis of the column structure with column extraction method.The mode,deformation and strength of the column after the failure of the front column,single cable and the rear column are studied respectively.The simulation results show that under the three failure conditions,none of the components yielded,and the column support structure system meets the performance requirements of progressive collapse prevention.
