摘要

The fatigue and short-time load tests of indoor scale models for orthotropic steel bridge deck with ERS pavement structure were investigated. Results showed that the longitudinal and transverse fatigue strains in the surface and bottom of deck pavement structure were divided into four stages. The maximum fatigue tensile strain of the surface of deck pavement was 160 με, transverse fatigue strain was changed from -70 με to 30 με, and longitudinal fatigue strain was larger than transverse fatigue strain. Stains in the bottom of deck pavement structure were all compressive strain. Under short-time loading, the stains in the bottom of deck pavement structure were compressive strain, and its values were within -5με. The longitudinal strain in the surface of deck pavement structure were ranged from -45 ue to 35 με, while transverse strains were ranged from -100 με to 80 με. The results from finite element had similar rulers with the results from actual measurements.
