| 摘要： | Although the use of curved and skewed bridges continues to increase steadily throughout the country, certain aspects of their behavior during construction and while in service still are not well understood. The effects of design, fabrication, and construction on the geometry and load distribution in a curved or skewed bridge system are areas in which further study and understanding are required. The construction of both curved and skewed bridges in the I-99 Advanced Technology Test Bed provides a unique opportunity to investigate curved and skewed structures not only during their construction but also while in-service. Two objectives were defined for this project: (1) the development and maintenance of data acquisition capabilities for instruments on two structures in the I-99 corridor identified as bridges 207 and 314; and (2) the development and comparison of accuracy of three different numerical models to construction data and/or to each other. / NOTE: Final rept.
