Abstract: Considering the slip between steel girder and concrete slab, experiments of fundamental dynamic characteristics and dynamic response of steel-concrete composite beam under moving load are carried out. Then comparative analyses between the experimental, theoretical and numerical results are conducted, showing good agreement. The results show that due to the flexible shear connectors, the relative slip occurs between the steel girder and concrete slab of the composite beams under external loads, which significantly influences the dynamic response of the composite beams.

Key words: civil engineering, steel-concrete composite beam, interface slip, dynamic response, moving loads
