AbstractAn original concept is presented for the durable rehabilitation and strengthening of concrete structures. The main idea to use ultra-high performance fibre reinforced (UHPFRC) complemented with steel reinforcing bars protect strengthen those zones structure that are exposed severe environmental influences high mechanical loading. This efficiently combines protection resistance properties UHPFRC significantly improves structural rehabilitated in terms durability. has been validated by...
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 embrace novel solutions that could specific challenges related the cost, speed durability, service life their projects. There are hundreds bridges worldwide that, largely past decade, utilized UHPC. These applications range from minor field-cast closures precast segments for long-span kilometer-long...
Abstract Mit dem zementgebundenen Ultra‐Hochleistungsfähigen Faserverbund‐Baustoff UHFB steht ein neuartiger Baustoff zur Verfügung, der sich durch hohe mechanische Festigkeiten und Dauerhaftigkeit auszeichnet. wird in Schweiz seit ca. 20 Jahren für die Instandsetzung Verstärkung bestehender Stahlbetonbrücken eingesetzt. In diesem Bericht zunächst Bilanz aus mehr als 400 UHFB‐Anwendungen gezogen. Die Erkenntnisse zahlreichen Anwendungen beim Einbau von auf Brückenplatten werden derart...

'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 resistance and durability of structural elements in reinforced concrete. This technical paper is intended serve design enhancement concrete bridges. After summarizing properties UHPFRC terms performance, analytical rules are presented calculate increase strengthened R-UHPFRC. Three...
Typical structural health monitoring systems employ limited numbers of sensors capable measuring discrete local behaviours. However, practical challenges arise as these sensor arrays cannot cover all areas interest. To address this challenge, article introduces a novel method for twinning dynamic behaviour by constructing finite-element-model-based digital twin, enabling the observation non-sensor positions crucial downstream tasks. The approach utilises streaming data, e.g., displacement...
The use of ultrahigh-performance fiber-reinforced concretes (UHPFRC) improves the structural response and extends durability concrete structures. Three basic configurations for elements combining UHPFRC reinforced normal strength are proposed with regard to typical demands on rehabilitation projects. They fulfill a protection function resistance can be increased if required. flexural these composite UHPFRC–concrete is investigated an original analytical cross-sectional model in parametric...
AbstractIn January 2011, the Swiss Society of Engineers and Architects (SIA) published a series standards for existing structures. The standard entitled 'existing structures—bases examination interventions' specifies principles, terminology appropriate methodology dealing with This is complemented by which treat specific items regarding 'actions on structures', concrete, steel, composite, timber masonry structures' as well 'geotechnical aspects structures'. It expected that these will...
Condition assessment in the Swiss bridge management system (KUBA-MS) is performed on element level. Five condition states are defined based visual appearance. In order to forecast of any given at time a relationship must be established between age and its state. This relationship, which describes evolution, can obtained empirically from statistical analysis pairs consecutive assessments (inspections). Markov chains used KUBA-MS represent evolution transition probabilities determined using...
