| مستخلص: | 69A3551747117 A Digital Twin (DT) approach is proposed as one potential step to the development of an autonomous (or semi-autonomous, referred to as ‘autonomous’ henceforth) load rating procedure for precast reinforced flat slab concrete bridges. The load rating is an approach to address the load-carrying capacity of in-service bridges. Full-scale laboratory testing was conducted on a bridge slab that was extracted from a de-commissioned bridge. The ultimate moment capacity of the slabs was assessed through the implementation of a bending test. The slabs were instrumented with strain and acoustic emission sensors to capture crack propagation and strain under a stepped loading procedure. Finite element modeling and the model calibrated in the experimental study under different loading conditions were conducted. A digital twin of a single slab of a precast flat slab bridge near Abbeville, SC, was developed. Different scenarios were examined to obtain an enhanced understanding of the behavior of one precast reinforced flat slab span. Field investigations were conducted, and the response of the bridge under daily traffic loading was utilized for calibration of the digital twin. The approach does not need any road closure and is cost-effective. |
