Self-Consolidating Concrete (SCC) and High-Volume Fly Ash Concrete (HVFAC) for Infrastructure Elements: Implementation. Report D, Load Testing and Monitoring of Bridge A7957 Initial In-Service Response

Bridge A7957 is the first bridge superstructure implementation conducted by the Missouri Department of Transportation (MoDOT) employing self-consolidating concrete (SCC) and high-strength self-consolidating concrete (HS-SCC) in its primary supporting members. The objective of this research was to perform an in-situ evaluation of Bridge A7957 to establish its baseline response and compare existing differences between the different spans’ behavior (in particular the first and third spans which have same geometrical characteristics). To fulfill this goal, a field load test strategy was elaborated and carried out to evaluate the bridge’s behavior under different static load configurations. During the field load test, embedded vibrating wire strain gauges (VWSGs) recorded strain variations at instrumented sections. In addition, an automated total station (ATS) measured the girders’ vertical deflection at critical sections. Based on field results, the precast, prestressed girders’ response of the different spans was compared, and lateral load distribution factors were obtained from field measurements and using the American Association of State Highway and Transportation Officials Load and Resistance Factor Design (AASHTO LRFD) Bridge Design Specifications. No significant difference between the spans’ behavior was observed during the live load tests. The load distribution factors estimated from the AASHTO LRFD approach resulted in more conservative values compared to the measured load distribution values.
