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

Table 13

The relation between deflections and strain and fatigue loading times for carbon-fiber-reinforced plate (corroded by carbonization) under the 200 kN load.

Fatigue cycles (10^4)	Y-5 (με)	Y-1 (με)	W-1/2 (mm)
0	212.2	−323.2	1.021
50	237.4	−365.8	1.124
100	261.5	−393.4	1.278
150	290.6	−425.6	1.401
200	314.7	−466.2	1.724

Note. W-1/2: midspan deflection, Y-1: compressive strain at the top of the midspan, and Y-5: tension strain at the bottom of the midspan.
