Abstract

Lap splice is a critical issue in the structural performance of Reinforced Concrete members. In the present study, the lap splice length of rebars was theoretically studied. On the basis of the bond behavior in the lap splice, a simplified design method was developed to predict the lap splice length of rebars under tension force. In the proposed method, local bondslip relationship between rebar and concrete was considered. The predicted tensile strength of the splice bars were compared with the 539 existing splice tests results. On the basis of pull-out test results, the proposed model was modified to predict the lap splice length of rebars in the beams using new materials. The predictions agree with the test results.
