Cold stiffening of the plate of Orthotropic Steel Deck (OSD) of bridges can be achieved by adding a layer of Ultra-High Performance Fiber Reinforced Cementitious Composite material (UHPFRC) on top of the deck plate by composite design, thus expecting to re ...
A reliable novel monitoring approach is developed to assess the structural condition of reinforced-concrete bridge elements. The approach is based on combining acoustic emission technique and strain gauge measurements, and it is illustrated by a case study ...
‘Structural UHPFRC’ stands for Ultra-High Performance Fibre Reinforced Cementitious Composite material, that is, complemented by reinforcing steel bars forming a R-UHPFRC layer with the goal to enhance the resistance and durability of structural elements i ...
This paper introduces the uniformity factor mu(2) for considering the local fiber distribution within elements made with Ultra-High Performance Fiber Reinforced Cementitious Composites (UHPFRC). The influence of mu(2) on the strain-hardening response of UH ...
The use of Reinforced Ultra High Performance Fiber Reinforced Cementitious Composite (R-UHPFRC) materials in the strengthening of existing infrastructure has been more broadly exploited in recent years, although the main domain of application pertains to t ...
Timber-Concrete Composite (TCC) structures allow taking synergistic advantage of the properties of both materials to optimize the overall performances in terms of lightness, slenderness, acoustic insulation, vibrational behaviour and environmental footprin ...
The biaxial flexural response of strain-hardening UHPFRC circular slab element is investigated experimentally and analytically using the ring-on-ring test. The Digital Image Correlation (DIC) technology is applied to capture the 3D full-field of strain and ...
Ultrahigh-performance concrete (UHPC) offers significant potential to address a variety of needs in bridge design, construction, and performance enhancement. Bridge owners have shown willingness to embrace novel solutions that could address specific challe ...
This paper presents the results of 28-month-long monitoring of a slab portion of the Chillon viaducts in Switzerland using strain gauges and thermocouples. This post-tensioned reinforced concrete structure was strengthened with a layer of reinforced ultrah ...
Constructed in 1969, the Chillon viaducts constitute a vital component of the Swiss roadway network. The bridge deck was strengthened in 2015 by means of an Ultra High Performance Fiber Reinforced Cement-based Composite for alleviating the effects of deter ...
On November 11, 2017, the world's first railway bridge built in reinforced UHPFRC on a main railway line lane was put in service. The building project of the Swiss Federal Railways was realized within a replacement project of a double‐lane railway bridge o ...
For assessment of existing reinforced-concrete bridges, only few rules and recommendations are available, and engineers meanwhile apply design codes for new bridges to evaluate the fatigue safety of existing bridges leading to non-realistic approaches and ...
