| Abstract: | Based on the deflection theory and equal-substitute beam method,the reasonable rise-span ratio and height-span ratio were suggested.A single-tower suspension bridge was designed according to the proposed rise-span ratio and height-span ratio,and was compared with a three-tower suspension bridge.According to the results,the number of main cables and the tower's construction cost of a single-tower suspension bridge reduced by 14% and 3.5%,respectively,as compared with a three-tower suspension bridge.The ratio... |
