The most widely used shear connector of steel‐concrete composite beams is the well‐known headed stud and it can be used for innovative bridge girders with trapezoidal webs embedded in concrete slab as well by horizontally placing the studs on the embedded steel part. Another option for trapezoidal web girders is the closed or open cuts on the corrugated web profile with rebars. In literature, experimental tests and investigation of these kind of shear connectors of embedded steel webs can be found. The focus of the research presented in the paper is on the ductility of embedded trapezoidal corrugated webs with additional mechanical shear connectors. Previous researches have already found that these kind of innovative shear connections have a really advantageous ductile behavior, however further analysis is useful to confirm and investigate their behavior in more details. Force‐displacement diagrams of push‐out experiments of corrugated steel profiles embedded into concrete slab are published in literature and those diagrams serve as a basis of this study. Both elastic and plastic phases of the curves are evaluated, also ductility is analyzed according to the principles of Eurocode.
