Sažetak
An experimental investigation to determine bond stress, free-end slip, and relative deformation between a reference plane in the masonry and an original coplanar point on the steel (slip) is conducted. Stack pll-out specimens constructed of grouted nominal 6-in. concrete or clay masonry units, reinforced with #4 or #7 bars, are subjected to monotonic or cyclic loadings. The methods for evaluating slip incorporated slip wires connected to linear variable differential transformers (LVDTs). Starin gages provide strain in the steel bars from which stresses in the reinforcing bar and bond stresses can be calculated. Free end slip is also collected. These data are useful in developing an understanding of the phisical mechanism associated with bond, slip, and bond deterioration. Ten specimen configurations were replicated three times. The nominal bond stress and free-end slip were obtained.
