Section 15 Concrete Reinforcement
January 2008 15-1 Section 15 Concrete Reinforcement Introduction This Section is intended to aid the bridge designer and detailer in the area of Concrete reinforced design and detailing. The tables in this Section simplify the design and detailing of Concrete Reinforcement splices and required covers. Also included are suggested details intended to ease the construction process and provide seismic resistance. Spacing The minimum spacing shall meet NYSDOT LRFD Bridge Design Specification Section requirements. The maximum clear spacing between parallel bars shall not be more than 1N-6O. The clear space between bars shall also apply to the clear distances between the contact splices and adjacent splices of bars. Bar spacings as indicated are always between the center of the bars unless otherwise noted as a clear distance. When Reinforcement in beams or girders is placed in two or more layers, the bars in the upper layers shall be placed directly above those in the bottom layer.
15.4.2 Reinforcement Splicing 15.4.2.1 General Splicing Guidelines For #11 bars or smaller, splices can be made by lap splices with wire ties, mechanical connectors (from the Materials Bureau approved list), or by welding provided it is in accordance with the NYSDOT Steel Construction Manual (SCM), Section 7, Part D. Tack welding is not
