Study on Fatigue Characteristics of Carbonation Erosion Prestressed Hollow Slabs in Whole Life Cycle

Table 15

Trend of dynamic displacement of test plates under 2 million fatigue cycles.

Degree of erosion	Reinforcement method	Crest (mm)	Trough (mm)	Amplitude (mm)
Not eroded	Carbon fiber cloth	0.39	−0.32	0.71
Not eroded	Sticky steel plate	0.37	−0.33	0.71
Carbonization	Carbon fiber cloth	0.53	−0.52	1.05
Carbonization	Sticky steel plate	0.52	−0.51	1.03
