Field Testing of Concrete Slab and Girder Bridges

T. A. Armstrong / E. V. Leyendecker / J. E. Breen

The report presents detailed results of a research program to investigate the feasibility of load distribution testing of a full scale reinforced concrete bridge structure in the field and to correlate that data with the data obtained from testing of an accurate scale model. The investigation tested the feasibility and durability of a new type of field strain gage application, tried a new method for field deflection measurement, and evaluated general operations in a remote location. The results obtained from multiple loadings of the full scale structure were compared with results from a 5.5-scale microconcrete model tested in a laboratory. The results were also compared with similar laboratory tested models differing only in skew angle and design loading. (BPR abstract)
