| Abstract: | A new type of ground-supported cable arch structure was proposed in the paper.Compared with other types of cable arch structures,the new one can obtain relatively high clearance,good architectural function and effect.Mechanical arch and cable arch models with span of 60 m and rise-to-span ratios of 0.2,0.3 and 0.4 were created.The mechanical performances including initial force,strength,stiffness,dynamic characteristic and stability performance plus the material costs were compared between the arch and cabl... |
