Structural performance of splice connector for precast concrete structures

This paper presents the test results of nine newly proposed splice sleeve connectors under incremental direct tensile load until failure. The configurations of the sleeve connectors were varied among the test specimens and their performance under direct tensile load was evaluated based on the load-displacement graphs, ultimate loading capacities, displacements and failure modes. The failure modes observed from the testing signifies the importance of grout-rebar bond, grout sleeve bond, tensile capacity of spliced...
