摘要:Mechanical performance of a new type of fabricated composite floors was studied. It was concluded that the local buckling of the upper flange of the thin-walled steel beams occurred along the whole upper flange of the thin-walled steel beams of the composite floors presented here, which showed that properly strengthening the upper flange of the main steel beams was necessary. It was also seen that the boundary condition at end of the main steel beam had no evident effect on vertical displacements of the specimens. Distribution of strains along height of the steel beam agrees with the plan cross-section assumption, which may be used as foundation of determining the formula of bearing capacity of the composite floor.
