Dimensioning of Structures made of UHPFRC

IABSE Reports, 2010
<p>Ultra high performance fibre reinforced concrete (UHPFRC) is a new construction material that enables the construction of slender and aesthetically appealing structures. First applications in structural engineering demonstrate the potential of this new building material.

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 ...

Blast-resistant performance of UHPFRC: An experimental study and optimal steel fiber content

International Journal of Protective Structures
This paper investigates the blast-resistant behavior of Ultra-High Performance Fiber-Reinforced Concrete (UHPFRC) slabs through close-in detonation tests. The UHPFRC was produced using locally sourced materials from Vietnam.

Shear and Flexural Behavior of UHPFRC‐NC Composite Beams Reinforced With High‐Strength Steel and Steel Fibers Under Static and Cyclic Loading

The Structural design of tall and special buildings
This study numerically investigates the shear and flexural behavior of ultra‐high‐performance fiber‐reinforced concrete (UHPFRC) beams with high‐strength steel (HSS) reinforcement under both static and cyclic loading.

Comparative investigation on tensile behaviour of UHPFRC

Materials and Structures, 2021
The recent advent in the field of cementitious composites with the emergence of high and ultra-high performance fiber reinforced concretes (HPFRC and UHPFRC) is considered a great opportunity in infrastructure accelerated construction, strengthening and repair.

Bond behaviour of reinforcing bars in UHPFRC

Materials and Structures, 2015
This paper deals with the experimental determination of the bond behaviour between ultra-high performance fiber-reinforced concrete (UHPFRC) and reinforcing bars (rebars). An experimental campaign has been carried out to assess the bond behaviour considering different rebar diameters, different embedment lengths and different concrete covers.

UHPFRC‐Fertigteilsegmente für einen nachhaltigen und ressourcenschonenden Betonbrückenbau

Beton- und Stahlbetonbau, 2023
Viele der gegenwärtig in Deutschland genutzten Betonbrücken weisen alters‐ bzw. bauartbedingt einen defizitären Zustand auf. Zudem tragen auch gestiegene Verkehrsbeanspruchungen dazu bei, dass viele der Brücken mittelfristig ersetzt werden müssen ...

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.
