FE Analysis and Tension Test of a Mortar-Filled Head-Splice Sleeve
Recently, a new type of splice sleeve system, mortar-filled head splice sleeve has been developed. The bond capacity of the mortar-filled head splice sleeve (HSS) can be changed corresponding to the development length and the type of head. In this paper, a finite element (FE) analysis and a tension test of head-splice sleeve were performed with the parameter of the development length and type of head to analyze the bond behavior of a mortar-filled head-splice sleeve.
From the FE analysis, it was shown that 20N/mm3 of Kn, the stiffness of perpendicular direction at interface between bar and grout mortar, is suitable to simulate the bond-slip behavior. Test result showed that the specimen with head has two times higher bond strength than without.
