The propagation of shear diagonal crack with load cycles of PC beams is similar to that of the PPC elements. The crack width of PPC and RC elements is limited in the service stage. The crack width model defines the relationship between crack spacing and width. The control of cracking is applied through the reinforcement spacing [22]. The ACI318 code also adopts this method to limit crack [23]. The AASHTO specification applies the same method with the ACI318 code. The maximum reinforcement

An experimental study is proposed to investigate the high-cycle fatigue behavior of prestressed concrete box-girders. Special focus is on the shear diagonal cracks in the webs of girders, which is rarely investigated in the open literature. Laboratory fatigue tests were designed and conducted to study the propagation of shear diagonal crack of PC box-girder specimens under cyclic loadings. The development of stirrup strain, propagation characteristics of diagonal crack and the related factors are discussed in detail. A finite element (FE) model...
