Tensile Lap Splices Part I: Retaining Wall Type, Varying Moment Zone
Thirty-two concrete beams simulating retaining wall stems and containing reinforcing bar lap splices were tested to failure. Twenty-seven beams had no. 11 bar splices, four had no. 8 bar splices, and one had no. 9 main bars spliced to no. 11 dowel bars. Failures were typically of the splitting type. It was concluded that the 1965 AASHO specification for splices does not provide a safe guide unless it is modified. The second part of the report presents a tentative theoretical treatment of lap splice length based on several observed types of splitting failure. (BPR abstract)
