Abstract: The static loading tests on the two groups of eight profiled steel sheeting and Engineered Cementitious Composite (ECC) slabs were conducted, and their failure mode, bearing capacity, stiffness, strain distributions and slip behavior were investigated. The test results show that: compared with the composite slabs specimens without end studs, the slip value of profiled steel sheeting and ECC composite slabs specimens with end studs is larger at peak load, after reaching the peak load, the bearing capacity of those specimens decreased gently, showing a ductile failure mode. In comparison, the composite slab specimens without end studs show a brittle failure mode. The effects of shear span, of profiled steel sheeting thickness, of composite slabs height, and of end studs on the longitudinal shear performance and on the bearing capacity of specimens were analyzed. According to the experimental results, the calculation method for the longitudinal shear capacity of profiled steel sheeting and ECC composite slabs was proposed based on the m-k method in Eurocode-4 and on Code CECS273:2010, respectively. The calculated results were in a good agreement with the experimental results.
