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

Table 12

The relation between deflections and strain and fatigue loading times for a bonded steel-plate-reinforced plate under the 200 kN load.

Fatigue cycles (10^4)	Y-5 (με)	Y-1 (με)	W-1/2 (mm)
0	216.5	−217.9	1.11
50	225.7	−241.3	1.18
100	241.6	−260.1	1.28
150	253.1	−290.3	1.35
200	258.3	−325.6	1.43

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.
