STATIC AND FATIGUE TESTS ON PRESTRESSED CONCRETE RAILWAY SLABS

The fatigue properties of prestressed pretensioned concrete railway slabs are discussed. A theoretical study of the fatigue resistance of such members is first presented, followed by a description of laboratory tests on six beams. Test results are discussed and interpreted. The theory of fatigue failure is based on three diagrams including a failure envelope based on a limited amount of fatigue test data on prestressing strands and a diagram of the fatigue characteristics of plain concrete. The two failure envelopes are combined with curves expressing the moment-stress relationship for a given beam. The investigator is able to predict the critical loading. It is concluded that the test results check reasonably well with the critical fatigue loads predicted on the basis of the stated theory of fatigue failure.
