Vibration Measurement & Condition Assessment of Bridges
- CSIR-SERC carried out various investigations on the field to ascertain the Structural condition of the bridges, by specifying the upper limit on the vehicular traffic on the bridge to be allowed, both in terms of the weight and speed of the vehicle and also pointing out the problem areas in the bridge requiring immediate attention.
- These include the major bridges in India such as the Mahatma Gandhi Sethu, Godavari Rail cum Road bridge, Kaveri bridge at Kulithalai and Amaravathi which were instrumented and their dynamic load factor evaluated including development of dynamic characteristics.
- Forced vibration tests, response measurement of the bridge under controlled vehicular movement, ambient response measurement when normal traffic passed through the bridge were done.
