Abstract:Beams, 6 x 6 in. in cross section with a 32-in. span, contained a single, spliced #4 bar, or two #4 bars, spliced in the region of constant moment. Lengths of lap were 3, 6, and 12 in. and clear spacings hetwecn the lapped bars were 0, 1/2 and 1 in. Lapped lengths of 12 in. devclopcd yield point st,ross in both the single and double bars. Single-bar beams failed by splitting of the bottom cover. Side splitting occurred in all of the double-bar beams. High bond stresses mere developed. Load-deflection curves and ultimate loads showed little difference in strength between adjacent and spaced splices.
