Effect of fiber orientation on the in-plane tensile response of UHPFRC reinforcement layers

Eugen Brühwiler, Emmanuel Denarié, Maléna Bastien Masse

The application on existing Reinforced Concrete (RC) slabs of cast-on site Ultra-High Performance Fiber Reinforced cement-based Composite UHPFRC) layers is a very efficient reinforcement technique, currently spreading. For the design of these tensile reinf ...

Contribution of R-UHPFRC Strengthening Layers to the Shear Resistance of RC Elements

Eugen Brühwiler, Maléna Bastien Masse

To strengthen a reinforced concrete (RC) slab with deficient shear resistance, it is proposed to add to the top of the slab a 25-50 mm thick layer of ultra-high performance fibre reinforced cement-based composite (UHPFRC) with small diameter rebars (R-UHPF ...

Experimental investigation on punching resistance of R-UHPFRC–RC composite slabs

Eugen Brühwiler, Maléna Bastien Masse

An effective method to strengthen existing Reinforced Concrete (RC) structures is to add a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over the concrete slab to create a composite ele ...

Geometrical and material characterisation of quenched and self-tempered steel reinforcement bars

Eugen Brühwiler, Alain Nussbaumer, Marina Rocha Pinto Portela Nunes

Quenched and self-tempered (QST) steel reinforcement bars (rebars) are manufactured by Thermex or Tempcore processes. Characterization studies of QST rebars are mostly limited to reveal the hardened outer layer and some improved mechanical properties compa ...

Monitoring of strain profile variations in the RC slab of a short span railway bridge

Eugen Brühwiler, Vasileios Grigoriou

A novel monitoring scheme oriented towards the structural examination of reinforced concrete slabs subject to railway traffic action is presented. Monitoring is based on the measurement of the mean axial strain profile variation in the cross-section of the ...

Probability of observable flaw initiation at high cycle fatigue

Eugen Brühwiler, Vasileios Grigoriou

Fatigue evolution during the flaw initiation phase and under high cycle fatigue conditions is described at the level of the representative volume element by the probability that this element fails in a given period of time under given stimulus. This probab ...

Damage models for UHPFRC and R-UHPFRC tensile fatigue behaviour

Eugen Brühwiler, Tohru Makita

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 combin ...

Microstructural influence on the scatter in the fatigue life of steel reinforcement bars

Eugen Brühwiler, Alain Nussbaumer, Marina Rocha Pinto Portela Nunes

Fatigue damage accumulation and failure of steel reinforcement bars (rebars) is a stochastic process. Scatter can be influenced by the sensitivity of the short crack growth to the microstructural features, especially near the fatigue limit. This work inves ...

A direct monitoring approach for the fatigue safety verification of construction joint details in an existing post-tensioned concrete box-girder bridge

Eugen Brühwiler, Mark Anthony Treacy

To date, there have been few reports of fatigue problems in medium-span reinforced or prestressed concrete road bridges, primarily due to the high ratio of the dead load to live load in such structures. Where fatigue problems have arisen, they have general ...
