ABSTRACT
A new type of continuous slab-deck specimens based on high toughness cementitious composites (HTCC) were designed and manufactured at a 1:1 scale. During 2 million fatigue cycles, the specimen did not exhibit any cracks. The load-displacement curves of different fatigue stages were consistent, the specimen remained in the elastic range with a stiffness variation of 12.43%. Static load tests at different fatigue stages indicated minimal residual strain in the material, with HTCC exhibiting concrete strains around 40 με and steel strains below 20 με. The maximum steel stress was 25.8 MPa, well below the yield strength of 400 MPa. The static failure test shows that the cracking load is 25 kN. Once the crack width and rotation angle reached the limit value, which was defined as specimen failure, the failure load was 205.0 kN. When load to failure, it was found that the main crack has a long development period and the peak crack is 2.40 mm.
