Strength of Overlapped Deformed Tensile Reinforcement Splices in High Strength Concrete
The report describes a test series carried out in order to evaluate the strength of overlapped tensile splices in high strength concrete and the anchorage strength of deformed bars in pull-out test specimens similar to that of DS 2082. The influence of concrete compressive strength, splitting strength and fracture energy on the strength of overlapped tensile splices is evaluated on the basis of 22 tests. The test indicate that the fracture energy of concrete appears to be a more governing property to the strength of splices than the compressive strength and splitting strength. The results from the tests with overlapped splices is compared to the Danish Code of Practice for the use of Concrete, DS 411. The comparison show that extrapolating DS 411 for the design of overlapped splices in high strength concrete will yield more conservative results than in the case of normal strength concrete.
