AbstractThis paper describes the experimental testing of 48-year-old concrete bridge girders that were fabricated using lightweight concrete. After the bridge was decommissioned, three girders were transported to the Systems, Material, and Structural Health (SMASH) Laboratory at Utah State University (USU). The double-tee girders were tested to quantify the effective prestress, flexural capacity, and deck punching shear strength. The experimental results were compared with calculated values… Expand
A 95-Year-Old Concrete Arch Bridge: From Materials Characterization to Structural Analysis
TLDR
Structural analysis confirms that the 95-year-old concrete arch bridge meets today’s load requirements in terms of bearing capacity, serviceability state, and that the adopted structural improvements are effective, showing how combining numerical modelling and laboratory tests can contribute to the preservation of an old—though fairly simple—and valuable structure.
