Estimation of Failure Mode of Mortar-Filled Sleeve Rebar Splices

Abstract In order to establish a more rational structural design method for mortar-filled sleeve rebar splices, it is necessary analyze and evaluate factors affecting the performance of these splices. It very desirable be able quantitatively estimate failure mode splices at stage. A estimating presented from existing research not clear because boundary expressed in formulas. There are also limitations using methods based on limited number test variables, insufficient specimens, fact that only steel pipe sleeves were used. Therefore, general comprehensive estimation method, needs quantitative explicit fashion evaluated diverse variables. this study, as part an effort generate basic data establishment bond strength equations addition, examine suitability modes 303 evaluated. The evaluation results indicated proposed by study would yield with sufficiently practical accuracy.
