A three-dimension model incorporating the sag of cable, large displacement of structure and the effects of beam-column has been developed. The comparison of two supporting systems is done and a rational one is confirmed.

• 建立了考虑拉索垂度效应、大位移效应、梁柱效应等因素影响的新型斜拉桥和摩天轮组合结构的三维有限元模型,并在此基础上研究了两种不同的支承方式对结构性能的影响,提出了一种合理的支承方式;
