| Outline of Final Research Achievements |
The objective of this study is to clarify the influence of qulity of splices, position of splices, a number of splices at a certain section and spacing of splices on the mechanical properties of the splice itself and the RC beams.The test results express the lower behavior in load carrying capacity, ductility and cracking of the RC beams using low qulaity splices compared to the beam using perfect splices or the control beam without splices.To improve the properties of such splices, a new type of corrective splice is developed. RC beams using the corrective splices exhibit almost the same load-displacement relationship and crack width as a control beam without splices.
