DOI: 10.1016/j.istruc.2021.05.078
Abstract: Abstract Thermal actions have frequently been related to the cracking of concrete bridges. During the paving of hot-mix asphalt (HMA) on the bridge deck, a high temperature gradient will generate through the depth of the… read more here.

DOI: 10.1080/24705314.2023.2165606
Abstract: ABSTRACT Nothing-on-road bridge-weigh-in-motion (NOR-BWIM) leverages the response of an instrumented bridge to identify various aspects of traffic information. This system circumvents many of the current issues with traditional BWIM systems, such as lane closure, expensive… read more here.

DOI: 10.1177/16878140221076458
Abstract: Non-uniform temperature distributions of concrete box girders are induced by solar radiation depending on the structural shapes and shadows cast on them. Using a real-time shadow-selection algorithm and finite element method, the thermodynamic analysis of… read more here.

DOI: 10.12989/cac.2017.20.5.617
Abstract: Prestress force identification (PFI) is crucial to maintain the safety of prestressed concrete bridges. A synergic identification method has been proposed recently by the authors that can determine the PF and the excitation force simultaneously… read more here.
