Abstract:
In order to improve the longitudinal shear resistance between foam concrete and C-Channels, an investigation is carried
out on the shear connectors in foam concrete with cold-formed steel double C-Channels embedment. Twentyfour
tests have been carried out in two groups. Two types of connectors: flange connectors and web connectors are
installed using self-drilling screws for a rapid construction. The experimental results show that they can effectively
improve the longitudinal shear-resist capacity of the concrete. After the experiment, the specimens are dismantled for
an interior observation. Based on the observation, the form of damage, the failure mechanism was discovered, and
the equation of longitudinal shear capacity was developed. It is concluded that the failure involves independent slippage
between two C-Channels and the shear connection fractures. Since the composite structure requires sufficient
slip between the two materials, these types of shear connectors will have good enhancement for this type of composite
structures subjected to dynamic loads.
