| Abstract: | Based on researches and tests, the impact factor for prefabricated highway steel bridges is relevant to not only effective spans, but also the weight and velocity of moving loads, and decks of the bridges. Additionally, the revised formulation of the impact factor is made for the bridges. The conclusions drawn from tests may be a reference for the design and employment of the bridges. |
