Data for \"CAIT-UTC-REG28: Cost-effective Bridge Decks for Improved Durability and Extended Service Life\"

This project involves the experimental testing of a unique bridge deck specimen with a corrugated core that is bonded to the deck plate using structural adhesive. The specimen was supported and loaded using specially designed fixtures. Comprehensive instrumentation was implemented, including uniaxial, biaxial, and rosette strain gauges, as well as displacement transducers. The testing program comprised initial static tests, fatigue tests, and intermittent static tests conducted over a 5 million-cycle fatigue period. Analysis of the static test results revealed the degradation of the adhesive connection between the core and the deck plate due to fatigue loading, leading to changes in transverse load distribution and decreased deck stiffness. However, the structural integrity of the deck remained intact. This study shows the potential cost-effectiveness of using structural adhesive for constructing steel sandwich plate decks.
