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

Table 14

The relation between deflections and strain and fatigue loading times for steel-plate-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	254.5	−360.7	1.09
50	274.1	−375.9	1.13
100	286.9	−390.9	1.40
150	291.3	−410.2	1.52
200	308.2	−440.3	1.88

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.
