Executive Summary
Load testing of a 30 m span PSC box girder bridge as per IRC SP:51-2015, including instrumentation, staged loading, deflection monitoring and structural performance evaluation.
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
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
