| Abstract: | Measurement method using dynamic assessment of the existing bridge carrying capacity is much promising. Impact factor as an entry point, the paper makes a dynamic testing research based on parameters like increase coefficient of strain and frequency, and gives a qualitative assessment on reinforced concrete simply supported beams carrying capacity. Combining with T-beam dynamic and static test data, it verifies the feasibility of this dynamic test. |
