Abstract:
On the project described the negative reinforcing bars settled as much as 2 1/2 in. out of correct position. Various means for incorporating negative reinforcement at correct height in the finished structure are discussed. The method selected of grouting additional bars in grooves made with some bars encased in the concrete and some bars grouted into diamond-sawed grooves, give results identical with those to be expected for all bars normally encased; ultimate strengths conform closely to the plastic bending capacity of reinforced concrete according to deisgn methods originated by C. S. Whitney.
