Title: Welding of 2-inch Square Reinforcing Bars for Piers of Pit River Bridge
Author(s): Robert Sailer
Publication: Journal Proceedings
Appears on pages(s): 53-60
Abstract:Two-in. square reinforcing bars 60 ft long, were used for the main reinforcement fn the tall concrete piers of the Pit River Bridge. Since more than 8000 splices,. laps or welds., were required laboratory tests were made to determIne whether adjoining bars could be satisfactorily welded. Results of these tests, prior to construction, showed that satisfactory welds could be obtained if low-car-bon steel was used and if certain precautions were taken in the welding operations. The specifications for the steel and the necessary precautions are discussed. Tests of welds during construction confirmed the results of the laboratory tests.
