OVERLAP SPLICES FOR RIBBED BARS FOR FREE USE IN A CONCRETE STRUCTURE . NORDIC CONCRETE RESEARCH. PUBLICATION NO 7

The object of the investigation is to develop a simple splice construction with confinement, which can anchor at least the yield stress of the reinforcing steel under static load and which has a fatigue strength exceeding that of unspliced tensile reinforcement. Beam tests with lapped tensile reinforcement have been performed under static and dynamic load. Every lap is confined by a spiral. Parameters such as bar diameter, concrete strength, lap length and confinement have been varied. Analytical bond theory for laps has been used to calculate the resistance of the laps under monotonic load and also under repeated loading, resulting in fatigue. Based on the investigation three types of spiral confined laps are proposed for use anywhere in a structure, where there is enough space for the splice construction. (TRRL)
