英文摘要	To promote the application of green renewable materials in concrete composite slabs (CCSs) and study the flexural behavior of CCSs with different shapes, the bending performances of three CCSs with a SFRRAC base plate, one cast-in-site concrete slab of ordinary concrete and one CCS of ordinary concrete by steel bar truss (as recommended in the technical specification for precast concrete structures in Chinese) were compared through experiments. The carrying capacity, flexural behaviour and bi-directional mechanical properties of the specimens were systematically analyzed from the failure modes, load-deflection curves, load-bar strain curves, load-slip curves and crack distributions. Results show that the bending failure process of CCSs with a SFRRAC base plate is similar to that of the cast-in-site concrete slab of ordinary concrete and CCS of ordinary concrete by steel bar truss, as all of them went through the plastic phase, elastic plastic phase and failure phase with fully developed cracks and deflection. No sudden breakage or horizontal cracking of the connecting interface between the base plate and concrete topping was observed. The shape of the base plate has a major impact on the bearing capacity of the CCS with the SFRRAC base plate. When calculating the ultimate bearing capacity with the plastic yield line theory, the influence of the base plate shape on the plastic yield line position should be taken into account. © 2020, Editorial Department of Journal of Southeast University.
