Project Highlights
- 30 m span PSC box girder bridge
- 100-tonne test load using four 25-tonne vehicles
- Seven dial gauges installed at different locations
- Maximum permissible deflection of 34.5 mm
- Measured deflection within permissible limit
03
Scope of Work
- Staged loading and instrumentation
- Deflection monitoring at each load stage
- Crack-width measurement using crack-gauge microscope
- Evaluation of readings as per IRC SP:51

Deliverables
- Load test report and test results
- Deflection readings at each load stage
- Crack-width observations
- Structural performance evaluation
- Conclusion on safe load-carrying behaviour
Outcome
Under the full 100-tonne test load, measured deflection remained within the permissible 34.5 mm limit, confirming satisfactory structural performance.
