Concrete Beams and Columns with Bundled Reinforcement
This paper reports on tests of pairs of large beams with conventionally spaced and with bundled longitudinal reinforcement. The bundles of reinforcement used comprised groups of four No. 6, four No. 8, or three No. 9 touching bars. Pairs of beams were compared with respect to width of flexural cracks, steel stress distribution, deflection, and ultimate strength. No significant difference in behavior or ultimate strength was found for bundled as compared to spaced reinforcement.
Tied columns were tested by concentric loading to compare spaced and bundled longitudinal reinforcement consisting of twelve No. 6 or twelve No. 8 bars. Comparison with respect to ultimate strength indicated that bundling is a safe detailing procedure when adequate ties are provided. This true even for 6. 6% longitudinal reinforcement. Splicing of bundled reinforcement in columns was explored and found to be feasible.
