Foreward This report documents the findings of a phenomenology study that analyzes the performance of HERMES ground-penetrating radar technology. HERMES technology was designed for the evaluation of concrete bridge deck deterioration, with a particular emphasis on the detection of corrosion-induced delaminations. HERMES technology was developed by Lawrence Livermore National Laboratory through ...

The wind flow around twin-box decks is particularly complex due to the very important role played by slot distance between girders and presence of downwind box that immersed in wake upwind box. Detailed experimental studies on three-dimensional features this deck typology are certainly challenging, CFD simulations have not tackled problem so far. goal 3D LES piece research shed some light decks...

In order to explore the construction technology of prestressed steel strand–polyurethane cement composites for strengthening hollow slab beams, two reinforced test beams (L1, L2) and one unreinforced beam (L0) were subjected flexural static load tests. The deflection, ductility, stiffness, strain, bearing capacity each used summarize influence different reinforcement techniques on performance b...

Bridges in Ukraine are one of the most important components infrastructure, requiring attention from government agencies and constant funding. The object study was methodology for quantifying condition bridge components. Artificial Neural Network-based (ANN) tool developed to quantify technical literature analysis showed that cases datasets were obtained during inspection bridges solve problems...

The collapse resulted in the media’s search for immediate answers to the following two questions; why did the bridge collapse and who is to blame? Speculative answers to the first question were proposed by the “Average Joe” and structural engineering experts alike, and involved the usual suspects; the growth from microscopic to catastrophic lengths of undetected cyclic load-induced fatigue crac...

This research studies the structural behaviour of bridge deck slabs under static patch loads in steel–concrete composite bridges and investigates compressive membrane action (CMA) in concrete bridge decks slabs,which governs the structural behaviour. A non-linear 3D finite element analysismodels was developed using ABAQUS 6.5 software packages. Experimental data from one-span composite bridge s...
