    Abstract

    This paper describes the ultimate loads and failure modes of composite steel-concrete specimens when carbon nanotube is implemented. This paper also compares the load versus slip relationship of push tests under ambient temperature, at-fire exposure and post-fire exposure. Results from the experimental study demonstrated that the reduction of ultimate load and stiffness as temperatures increased. The at-fire exposure specimens showed a decrease in ductility as temperatures increased. Whilst, the post-fire exposure specimens showed an increase in ductility as temperatures increased. Even though carbon nanotube did not show increment in ultimate load, however the carbon nanotube reduced concrete spalling and cracking when compared to normal concrete under elevated temperatures.
