| Abstract: | The bridge lateral responses for 30 m-span pre-stressed T-sectional girder in the 2nd Songhuajiang Bridge and its 4 schemes of reinforcement under passeger train and cargo train are analyzed. The calculation result is checked by that of site experiment, reinforcement method of T-sectional girder is summarized and suggestions for the engineering in this bridge are provided. |
| Keywords: | vehicle-bridge interaction analysis pre-stressed concrete simple-support T-sectional girder reinforcement lateral amplitude traveling safety |
