Abstract |
The bridges where serious damages, defects, material degradations, etc. are not found can be presumed to have enough safety for the specified design loads, nevertheless, in many cases the loading carrying capacity is rated through loading tests. The safety specifications and manuals get no further than qualitative instructions for performing loading test or not. Some studies presented the improved appraisal methods for determining the load carrying capacity; however, the feasibility studies for loading test are scarcely carried out. This study examines an existing question, whether the loading tests are necessarily required in the safety assessment or not, and suggests an alternative for that via a statistical analysis for dozens of condition evaluation reports for concrete bridges.
