| 摘要： | Structural assessment of bridge P-0962 in MODOT District 8 involved both the sensing network of fiber-optic and electrical resistance strain gauges (ESGs). Sensing arrays were installed on the mid-span of the bridge to determine the performance of the fiber optic strain sensors for field applications and to provide in situ measurement capability for the strengthened bridge. Extrinsic Fabry-Perot Interferometric (EFPI) strain sensors were used to measure point strain. Dynamic and static load tests were Performed as well as finite element analysis. Scenarios are given for the load testing along with data filtering and processing details and performance of the fiber optic strain sensors for field applications. |
