Abstract Of Influence of (Coated) Stirrups on Overlapped Splice Strength of Epoxy Coated Deformed Bars
This paper investigates the influence of coated stirrups on overlapped splice strength of epoxy coated deformed bars. Six (6) beams of length 2550mmย ย 300mmย ย with lapped splice bars in constant moment region were cast and tested. The beams where cast with 16mm high yield diameter bars for both compression and Tension zone, 8mm high yield stirrups were used over the lap splices.
The ultimate moment from the test were used to determine the stress developed in the bars. The ratios of the test bond stresses and bond stress values using the tensile reinforcement yield stress , were used for comparison of the parameter under investigation. Coated and uncoated Transverse reinforcement was found to increase the splice strength of epoxy coated deformed bars, but uncoated transverse reinforcement was found to increase the splice strength of epoxy coated bars more than coated transverse reinforcement.
