T here- fo re, there are d ifferent fo rced perform ances betw een wt o types o f spat ial structures. In this paper, the com parisons betw een stayed cable- arch and cab le-arch structure, based on som e practical projec,t u sing the AN SY S prog ram, estab lish ing tw o num erica l m odels, including static perform ance and dynam ic perform ance, are carried out under the sam e loads. A ccord ing to the results, the smi ilarit ies and d ifferences of m echanic perform ance are summ ed up, w hich present that m echanic perform ances o f the stayed cable- arch structure are super ior to the ones of cab le-arch structure.
