Initial In-Service Response and Lateral Load Distribution of a Prestressed Self-Consolidating Concrete Bridge Using Field Load Tests
Bridge A7957 is the first Missouri Department of Transportation (MoDOT) infrastructure in which self-consolidating concrete (SCC) and high-strength self-consolidating concrete (HS-SCC) were implemented. The objective of this research was to monitor the initial in-service behavior of the precastprestressed concrete primary elements of Bridge A 7957. An initial series of diagnostic load tests was conducted on the bridge's superstructure. Embedded sensors recorded strain variations at instrumented girder sections during different load configurations. Lateral distribution factors were computed from experimental data, finite element models (FEM), and using the AASHTO LRFD Bridge Design Specifications which resulted in conservative values. No significant difference was observed between the SCC and conventional concrete members' response during this first series of field load tests.
