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

Table 11

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

Fatigue times (10^4)	Y-5 (με)	Y-1 (με)	W-1/2 (mm)
0	208.8	−290.3	1.06
50	221.7	−290.3	1.12
100	237.6	−307.1	1.29
150	247.1	−337.3	1.33
200	260.3	−362.3	1.44

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.
