Full-scale test to failure of a strengthened reinforced concrete bridge: calibration of assessment models for load-bearing capacities of existing bridges
2008 (English)In: Nordic Concrete Research, ISSN 0800-6377, no 2, 131-142 p.Article in journal (Refereed) Published
A reinforced concrete railway trough bridge has been strengthened and loaded to failure. The aim was to test and calibrate methods developed in the European Research Project "Sustainable Bridges" regarding: (a) condition appraisal and inspection, (b) load carrying capacity analysis, (c) monitoring and (d) strengthening of existing bridges. The tested methods proved to be useful and to give accurate predictions. A failure in combined shear, bending and torsion was reached for an applied mid span load of 11,7 MN. This was well predicted by enhanced methods but 20 to 50 % higher than ultimate load evaluated according to predictions based on common codes and models.
