Experimental Fatigue Evaluation of Prestressed Concrete-Filled Steel Tube I-Shaped Bridge Girders
This paper investigates experimentally the fatigue capacity of prestressed concrete-filled steel tube (CFT) I-shaped girders. The girder consists of steel plates, PT tendons, concrete, and steel shear keys. Three 10 m long girder specimens were prepared for different fatigue stress ranges and subjected to a three-point bending test producing a positive moment along the entire girder span. Displacement control was used to prevent sudden failure of the specimens. The test girder specimens exhibited fatigue capacities classified as Category B′ or C′ of the AASHTO criteria for positive and negative moment, respectively. The special testing arrangement used to produce the negative moment is presented, as well as the fatigue testing procedures and results. At the end of the paper, a modified equation for the S–N curve is derived for predicting the remaining life of the girder.
