Performance of cs-sleeve under direct tensile load: part 1: failure modes
Tensile resistance of a sleeve connector used to connect between two structural components by confining grouted reinforcement bars relies on the bond interaction among reinforcement bars, sleeve and grout. Slippage of the reinforcement bars is customary cause of damage in end-to-end grout-filled...

| Summary: | Tensile resistance of a sleeve connector used to connect between two structural
components by confining grouted reinforcement bars relies on the bond interaction among
reinforcement bars, sleeve and grout. Slippage of the reinforcement bars is customary cause of
damage in end-to-end grout-filled reinforcement connector under direct tensile force. In this study,
a total of nine specimens with different configuration, in terms of sleeve lengths, sizes,
configurations, rebar surface conditions and grouting material, were subjected to tensile test. This
paper presents the result obtained from tests conducted on the proposed CS-Series specimens and
discusses the failure mode as well as the mechanisms that governed the tensile resistance of the
specimens. The test data indicates that threads on reinforcement bar had significantly deteriorated
the bonding mechanism between reinforcement bars and grout. None of the specimens could
achieve the required strength. However, the understandings of the causes of failures obtained from
the study provided essential basis for future research. |
