| Abstract: | This paper simulates the different degree damage of the suspender by MIDAS/Civil Finite element software.Calculated and compared the bridge's dynamic properties in the different degree damage of the suspender.This provides a reference and basic data for understanding correctly the structural dynamic properties of double X-arch bridge in different states and evaluating reasonably the health status of double X-arch bridge in operational phase. |
| Keywords: | computer simulation double X-arch bridge dynamic properties suspender damage |
