Due to the importance of historical timber covered bridges throughout history, their preservation is necessary. However, conducting an accurate structural evaluation of these types of bridges has always caused difficulties to bridge engineers. This paper summarizes an investigation that was sponsored by the Federal Highway Administration and the USDA Forest Products Laboratory to develop a simple but accurate analytical model to analyze Burr Arch Truss bridges. A three dimensional model that included the splice joints that were used in the construction of the bridge was utilized in the analysis. The analysis was carried out using the STAAD finite element software. The displacement and strain results that were obtained from the analytical models were compared to those measured in the field.
