The analysis of the free vibration characteristic of the long-span arch bridge made of concrete filled in steel tube |
| |
| Abstract: | One part of this paper is about the calculation of free vibration characteristic which is possessed by a type of long span arch bridge with parallel ribs and a type of long span x type arch bridge both made of concrete filled in steel tube. After consulting some related caculations from other papers, the universal law of free viberation characteristic which belongs to long span arch bridge made of concrete filled in steel tube with parallel ribs is analyzed in this paper. The last part deals with the effect which intilted arched ribs have on the free viberation characteristic. This paper is aimed to offer referrence for further study. |
