Remote Electronic Data Gathering and Storage System (Supplement I),

摘要

The development,installation,and use of a remote electronic data gathering and storing system is described in detail. The system automatically gathered thermal data and joint displacement data from two specially instrumented highway bridges for a period of one year. The bridges were selected on the basis that they typified many highway bridges used in the New Jersey State and Interstate highway system,having steel superstructures,and reinforced concrete decks,and being of simple span,composite design. In general,the data system worked quite well with minimal interruption or data loss,thereby obtaining a continuous,multi-seasonal close look at the thermal and displacement behavior of skewed and non-skewed bridges. Data analysis and conclusions drawn therefrom are included in a separate report titled, 'The Relationship of Environmental Parameters to Displacement Responses of Highway Bridges.
