Field Testing of the Wolf Creek Curved Girder Bridge: Part II: Strain Measurements
The Wolf Creek Bridge is a curved, multi-girder three span steel composite bridge located south of Narrows, Virginia, that was completed in 2006. A finite element (FE) model of the bridge revealed that pier flexibility may be important in modeling the bridge. In addition, questions have been raised as to the effectiveness of the C15x33 diaphragms in providing lateral transfer of loads between members. This study was conducted as Phase II of a project for which the overall goal was to use field testing to obtain a better understanding of the behavior of multi-span curved girder bridges. The Phase I study was published separately. During Phase II, an array of 49 strain gages was installed on the superstructure of the bridge: 34 gages were installed on the four girders at the mid-point of the center span, and 15 gages were installed on the three diaphragm members located closest to mid-span. The bridge was then subjected to static and dynamic applications of a loaded dump truck for which the axle loads were quite close to those of an HS-20 truck. The static strains were measured when the truck was located at 19 different locations on the inner and outer lanes.
