The degree of interaction, which is referred to as the degree of composite action, is calculated through flexural tests. Yang et al. (2023) studied the flexural performance of four prefabricated steel-concrete beams (PSCCBs) with grouped bolt shear connectors under positive bending moments. They performed bending tests and finite element (FE) analysis to investigate the effect of pertinent design parameters on the flexural behavior of the PSCCBs. Song et al. (2024) introduced a novel timber-filled tubular composite beam consisting of cold-formed, thin-walled rectangular steel and timber. They conducted eleven four-point flexural tests on specimens comprised of different cross-section combination forms, interface connections, and tapping screws. Shi et al. (2022) proposed an innovative prefabricated composite beam consisting of two full-depth precast concrete (FDPC) slabs with the advantages of rapid assembly and construction compared to conventional composite beams. Moreover, FE models were developed and validated based on a full-scale flexural test. Bandelt et al. (2019) performed one full-scale flexural test on a composite specimen comprising the Girder-Slab system. Zhang et al. (2020) conducted eight flexural tests on steel-concrete composite (SCC) beams and investigated the failure modes, concrete slab strains, steel beam strains, and load-deflection curves. A summary of the previous studies is presented in Table 1 and Figure 2.
