he rehabilitation of existing bridges should always be the first investigated solution because it usually reduces construction costs, environmental impacts, and traffic disruption. Nonetheless, bridges are too often replaced due to the lack of effective st ...
To explore the governing mechanism underlying the tensile fatigue behavior of Ultra-high Performance Fiber Reinforced Cementitious Composites (UHPFRC), this study tested eight specimens using four advanced non-destructive measurement techniques. First, mag ...
A framework to engineer existing structures, in particular bridges, and novel engineering methods and technologies are presented to extend the service duration of existing bridges while meeting the requirements of modern use. Accurate determination of brid ...
Renewal of reinforced concrete bridges by means of UHPFRC – Experiences from 400+ applications. Ultra-High-Performance Fiber-Reinforced Cementitious composite UHPFRC is a novel building material that is characterized by high mechanical strength and durabil ...
This paper outlines concepts using ultrahigh-performance fiber-reinforced composite (UHPFRC) to address structural deficiencies in modern fixed railway track systems of concrete, focusing on enhancing structural safety, durability, and fatigue resistance. ...
This article focuses on the characterization of the early-age properties of Ultra-High-Performance Fiber-Reinforced Cementitious Composite (UHPFRC), which is becoming popular for designing lightweight and durable structures. Due to the large proportion of ...
Examining the performance of an existing bridge requires information on several aspects, such as design choices, material properties, and ongoing degradation processes. It often happens that some critical information is not available. The traditional appro ...
The transfer of technology from research to structural engineering and construction practice is illustrated using two cases of the implementation of innovative engineering methods and technologies in the renewal and 'upcycling' of existing bridges, namely ...
This paper investigates the high cycle tensile fatigue behavior of steel rebar reinforced − UHPFRC elements, at a fatigue load ratio, i.e., R-ratio of 0.3, representative for structural applications. Prior to testing, magnetoscopy is conducted on each spec ...
This paper investigates the fracture mechanism of ultra-high-performance fiber-reinforced cementitious composites (UHPFRC) using acoustic emission (AE), digital image correlation (DIC), and magnetoscopy testing. Four specimens undergo uniaxial tensile load ...
