Through the ultimate bearing capacity test of 2 prestressed concrete T-beams, the cracking load, the failure load, the control section stress, and the crack and deformation were tested respectively. The mechanical behavior differences of retard-bonded prestressed concrete between T-beam and ordinary prestressed concrete T-beam were contrasted. The test results show that: the change rule of the measured value of deflection and strain is basically the same between the retard-bonded prestressed concrete T-beam and the ordinary prestressed concrete T-beam. Compared with the measured value of the o...
