Abstract
We conducted the test on the assumption of lap splices that are located at the plasticity hinge area in beams under tensile loading. In order to clarify of the structural characteristic of lap splices in the range of plastisity due to rate the individual effect on that, we investigate the following contents: 1) Relationship between failure mode and spliced arrangement 2) The stiffness of spliced members 3) The structural criterion of the splices to ensure the same performance as non-spliced member 4) Resistance mechanism of splices and share of stress in the splices 5) The stress distributions in spliced main bars 6) The. ratio of bond strength in the straight parts of spliced bars to the total strength of splice The effect of the slope of moment in the members and of the compression strut from the bents of the spliced bars to compression zone of the members on the ductility of lap spliced members should be confirmed by supplementary examination.
