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

Table 16

Dynamic displacement growth rate of test plates under 2 million fatigue load cycles.

Degree of erosion	Reinforcement method	Crest (mm)	Trough (mm)	Amplitude (mm)
Not eroded	Carbon fiber cloth	1	1	1
Not eroded	Sticky steel plate	1	1	1
Carbonization	Carbon fiber cloth	35.90%	62.50%	47.89%
Carbonization	Sticky steel plate	40.54%	54.55%	45.07%

Note. The dynamic displacement data under the 2 million fatigue cycle test of the uneroded test plate are set as 1.
