Analysis of a Sudden Failure of RC Roof Slabs in a Steel Mill
Two Reinforcement Concrete (RC) roof slabs, with a size of 1.5 m×6 m, suddenly dropped from the roof after 32 years service in a steel rolling workshop of a steel mill. By in-situ inspection and lab investigation, it was found that the failure of the roof slabs were due to the severe corrosion of the prestressed steel bar, which was induced by concrete degradation connected closely with the service environments of the slabs.
