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

Figure 23

The relation between midspan tensile strain and fatigue cycle times for different test beams. B-1: uneroded carbon-fiber-reinforced test plate, B-2: uneroded bonded steel-plate-reinforced test plate, B-3: carbonized eroded carbon-fiber-reinforced test plate, and B-4: carbonized eroded bonded steel-plate-reinforced test plate.
