“…Several methods have been proposed to estimate the restraint moments which will develop at the continuous support. The method most commonly used to date was first published by the Portland Cement Association in 1961 and extended in 1969 , since then, various computer programs have been developed to further refine the analysis and design of this type of structure (Sinno and Furr [1972], Tadros et al [1975], Suttikan [1978] and Glikinetal[1987]).…”

This report summarizes an experimental investigation carried out to evaluate the effects of strand debonding on the behavior of precast pretensioned bridge members made continuous with a cast-in-place slab and diaphragm.Shear and flexural capacity were evaluated and the experimental results compared to the results obtained using the PCA and CTL (proposed) analytical methods.Four continuous specimens were fabricated and tested.Three specimens consisted of Type-I AASHTO girders continuous with a cast-in-place slab and diaphragm The fourth specimen consisted of Indiana Type CB-27 box girders also continuous with cast-in-place slab and diaphragm.The effect of time-dependent creep and shrinkage deformations on the capacity of the girders at the continuous supports was investigated in this study. Also addressed in this report is the effect of limiting the stress at the extreme compression fiber, near the continuous suppose, to allowable working stress values on the load carrying capacity of continuous members.
