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 ...

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.
