Experimental study on the bending performance of a precast, pretensioned high-strength concrete I-girder with pretensioned double broken strands
Deformation
The deformation curve of the girder under different loads is symmetrical around the midspan in the bending failure process, as shown in Fig. 20a. Under a single-point load of 0 kN-750 kN, the maximum deflection of the midspan and the…
