FIRST YEAR MONITORING OF THE FIRST AIR-ENTRAINED HIGH-PERFORMANCE BRIDGE IN NORTH AMERICA

By instrumenting the first air-entrained high-performance bridge in North America, the characteristics and reliability of thermocouples and vibrating wire extensometers could be tested on a real structure. The experimental structure was selected for the simplicity of its conception and operation. The temperature variations in the concrete slab generally followed ambient temperature cycles. The evolution of total strain included thermohygrometric, as well as physical-chemical phenomena in the concrete. The periodic variations noted in temperature and strain also apply to other concrete structures that are influenced by seasonal thermohygrometric cycles.
