The Use of Shear Connectors for Enhancing the Performance of Steel–Concrete Composite Beams: Experimental and Numerical Assessment

다국어 초록 (Multilingual Abstract)

Structural steel and reinforced concrete are the main materials used in civil structures, and each has its own advantages and disadvantages. Nonetheless, when they are combined together to form a composite material, they result in tremendous advancements. There exist diff erent devices to attain the composite action between steel and concrete among which is the shear stud connector that represents one of the most commonly used methods in composite construction, and it is the scope of this study. This monograph examines the degree of shear connection in steel–concrete composite beams depending on the properties of the shear connectors, where mild and rigid shear connectors where studied. It has been concluded via a non-linear numerical analysis backed by experimental testing that the capacity and the deformation of composite beams depend on the confi guration and the mechanical properties of the shear connectors. Moreover, a simplifi ed model to predict the degree of shear connection and the capacity of the composite beam was proposed.
