Cyclic behavior of UHPFRC under compression

Cement and Concrete Composites, 2019
Abstract The research field of constitutive modeling ultra-high performance fiber reinforced concrete (UHPFRC) is in current development. Few experimental results were reported for the material under uniaxial low-cycle loading, and consequently, there is a gap in constitutive propositions to predict its behavior. Thus, one purpose of this research is

New UHPFRC Bridges in Czech Republic

IABSE Reports, 2022
<p>This paper deals with new UHPFRC (Ultra High Performance Fibre Reinforced Concrete) bridges produced or constructed in 2018 in Czech Republic. The paper includes a short description of 3 unique pedestrian bridges with load bearing structure made of UHPFRC and 2 steel bridges over the railway track with lost formwork for bridge decks and ...

Querkraftversuche an profilierten Spannbetonträgern aus UHPFRC

Beton- und Stahlbetonbau, 2019
AbstractUltrahochfester faserbewehrter Beton (UHPFRC) ist ein Faserverbundwerkstoff, der durch sehr hohe Dichtigkeit und Festigkeiten charakterisiert ist. Dadurch ergeben sich im Fertigteilbau, insbesondere für Spannbetonträger, völlig neue Möglichkeiten für gewichtsreduzierte, schlanke und dauerhafte Konstruktionen.

Experimental Testing of Layered UHPFRC Beams

Advanced Materials Research, 2014
Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) is fine-grained cement-based material characterized by high compressive strength (exceeding 150 MPa) and high modulus of rupture (over 15 MPa). The results of strengths depend on the size of the tested element, the loading rate and the boundary conditions during a testing.

Segregation of Steel Fibres of UHPFRC

Solid State Phenomena, 2018
The mixture of ultra-high performance concrete is often supplemented by steel fibres which can significantly improve the fracture energy of the concrete. The incorporation of steel fibres results in especially a significant increase of tensile strength and minimize the risk of brittle failure.

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.

UHPFRC - Mechanisms and applications

2017
Ultra-high Performance Fibre-Reinforced Concrete (UHPFRC) has emerged around 25 years ago as a fruitful result of dedicated research efforts based on the combination of three main ideas : Strength and compactness improvement of cement materials by intense reduction of the water to binder ratio, which was made more and more possible and efficient with R&

UHPFRC Segmental Footbridge Velodrom in Brno

Footbridge Chur 2025, Chur: in situ
<p>The new crossing of 7 road lines is designed as a single-span parapet beam with overhanged parts. The superstructure is composed of 7 UHPFRC segments that are prestressed by unbonded strands. This approach was adopted because of the footbridge’s temporary life in this place.

Strengthening Paudèze bridges decks using UHPFRC struts

IABSE Reports, 2019
<p>Paudèze bridges are two 400‐m long parallel highway bridges located in Switzerland and opened to traffic in 1974. After over 40 years of service life, both bridges must be completely rehabilitated and strengthened while constantly maintaining 2 traffic lanes in both directions.</p><p>The bridge deck slab was strengthened using ...
