ABSTRACT
The components of the TR histories were obtained at the same time and place as the TT history. The TR histories represent portions of ten minutes of strain data recorded while the bridge was in normal service. During this ten minute period, nine significant loadings took place (corresponding to the presence of single or multiple trucks on the bridge) separated by periods of light vehicle traffic. TR histories used in the tests reported here were developed from portions of this recorded data, and include combinations of loadings representing both significant events and light vehicle traffic [14].
