An analysis of the influence of pier and abutment's stiffness on vibration of bridge span |
| |
| Abstract: | Abstract A special model of pier\|bridge joint system was established. The transversal stiffness of pier top was taken as an index to study the influence of pier on dynamic response of beam, and further study was made on this problem using beam\|pier stiffness ratio. A reference standard for simplified dynamic computation was raised. |

| Keywords: | transversal fundamental frequency of beam critical transversal stiffness of pier top critical transversal beam\|pier stiffness ratio |
