Exploring Concepts For UHPFRC Bending-Active Footbridges

Footbridge 2022, Madrid: Creating Experience, 2022
<p>This contribution describes two concepts for lightweight bending-active footbridges, and the corresponding experimental prototypes made of ultra-high-performance concrete (UHPFRC). The first prototype (bending- active bow-string concept) has a span length of 5.4 m and is composed of a thin UHPFRC prestressed slab, a UHPFRC deviator and ...

Damage models for UHPFRC and R-UHPFRC tensile fatigue behaviour

Engineering Structures, 2015
Ultra-High Performance Fibre Reinforced Composites (UHPFRC) is a cementitious material showing relatively high tensile strength and significant tensile strain-hardening behaviour (given a certain volume of fibres). Adding a layer of UHPFRC or UHPFRC combined with steel rebars (R-UHPFRC) to structural members is an efficient method for strengthening of ...

Übergangskonstruktionen aus UHPFRC für den Integralbrückenbau

Beton- und Stahlbetonbau, 2022
AbstractDank der Bereitstellung von normativen Regelungen für den Entwurf und die Bemessung nimmt die Anzahl von Integralbrücken weltweit deutlich zu, sowohl durch Neubauten als auch durch die nachträgliche Integralisierung von bestehenden Bauwerken.

Reinforced UHPFRC Tension Chords

IABSE Congress, Chicago 2008: Creating and Renewing Urban Structures – Tall Buildings, Bridges and Infrastructure, 2008
<p>Ultra high performance fiber reinforced concrete (UHPFRC) has a compressive strength in the range of 200 MPa as well as improved durability properties compared to normal strength concrete. By the addition of short steel fibers the behavior of UHPFRC in compression and tension is affected in a beneficial way.

Delayed Casting of UHPFRC Elements

Key Engineering Materials, 2019
Because of high durability and excellent material properties, innovative (thin-walled, shell) structures should be designed. Ultra - High Performance Fiber Reinforced concrete might be used for a specific application with very complex design and very complex shape.

Segmented footbridge made of UHPFRC

IABSE Reports, 2019
<p>The paper deals with the design and production of a segmented prestressed bridge made of Ultra High Performance Fiber Reinforced Concrete (UHPFRC) The footbridge is installed in the town of Příbor in Czech Republic. The UHPFRC or UHPC material in the Czech Republic gradually finds its way to interesting and unique design applications.

Feinprofilierte UHPFRC‐Trockenfugen für Segmentbauteile

Beton- und Stahlbetonbau, 2013
AbstractGegenüber der Ortbetonbauweise hat die Segmentbauweise mit Betonfertigteilen viele Vorzüge. Diese liegen zum einen in der qualitätsgesicherten und witterungsunabhängigen Vorfertigung im Fertigteilwerk, einer verkürzten Bauzeit sowie besseren Rückbaumöglichkeiten.

Verbundverhalten von CFK‐Spannbewehrungen in UHPFRC

Beton- und Stahlbetonbau, 2013
AbstractDie Kombination einer vorgespannten CFK‐Bewehrung (Carbonfaserverstärkter Kunststoff) und UHPFRC (Ultra High Performance Fiber Reinforced Concrete) ermöglicht es, filigrane und weitgespannte Konstruktionen zu errichten, insbesondere wenn es sich um gefaltete und gekrümmte Schalen handelt. Wegen der Unempfindlichkeit gegenüber Korrosion wird die
