International Perspective on UHPC in Bridge Engineering

Eugen Brühwiler

Ultrahigh-performance concrete (UHPC) offers significant potential to address a variety of needs in bridge design, construction, and performance enhancement. Bridge owners have shown willingness to embrace novel solutions that could address specific challe ...

Cold stiffening of orthotropic steel decks by a composite UHPFRC layer

Eugen Brühwiler, Lan Duan

Cold stiffening of the plate of Orthotropic Steel Deck (OSD) of bridges can be achieved by adding a layer of Ultra-High Performance Fiber Reinforced Cementitious Composite material (UHPFRC) on top of the deck plate by composite design, thus expecting to re ...

Fatigue Damage Factor Calibration for Long-Span Cable-Stayed Bridge Decks

Alain Nussbaumer, Cláudio Alexandre Pereira Baptista

Part 2 of the Eurocode 3 (EN 1993-2) proposes a straight forward fatigue verification method using a single heavy vehicle model (FLM3) and a damage equivalent factor, lambda, to represent the fatigue damaging effects of the real traffic on road bridges. Th ...

“Pocket-Monitoring” for the fatigue safety verification of bridge members in steel and reinforced concrete

Eugen Brühwiler

The fatigue safety of the reinforced concrete deck slab of a sixty-year-old steel-concrete road viaduct as well as the riveted steel girders of a 130 year old railway bridge was questioned based on the results of conventional assessment consisting in "re-c ...

A multi-scale based cohesive zone model for the analysis of thickness scaling effect in fiber bridging

John Botsis, Luis Pablo Canal Casado

A cohesive zone model (CZM) is proposed to assess the thickness scaling effect associated with fiber bridging during fracture. The CZM was developed through a multi-scale simulation approach and utilizes an embedded cell model of the Double Cantilever Beam ...

Large scale fiber bridging in mode I intralaminar fracture. An embedded cell approach

John Botsis, Georgios Pappas, Luis Pablo Canal Casado

Fiber reinforced composites can develop large scale bridging upon mode I fracture. This toughening mechanism depends on the constituents and the geometry of the specimen, and is especially important in unidirectional laminates when fracture is parallel to ...

Analytical approach for improving damage equivalence factors

Alain Nussbaumer, Nariman Maddah

The fatigue design of bridges under variable amplitude traffic loads is not straightforward. To simplify the task, the current Eurocode provisions apply fatigue load model 3 and damage equivalence factors (lambda). However, the fatigue load model and the d ...

Résistance au déversement des poutres métalliques de pont

Raphaël Thiébaud

Steel and steel-concrete composite bridges made of plate girders represent an economical structural form and are largely used for short and medium spans. Two parallel plate girders connected by cross-beams define a twin-girder bridge. This type of bridge t ...

Updating existing railway bridges based on monitoring data

Eugen Brühwiler, Mark Anthony Treacy, Marina Rocha Pinto Portela Nunes

Due to the important direct and indirect costs of the intervention, more detailed examination methods based on data as obtained from monitoring is suggested. This paper reports on an ongoing study to examine the fatigue safety of one standard bridge type, ...

A monitoring system for determination of real deck slab behaviour in prestressed box girder bridges

Eugen Brühwiler, Mark Anthony Treacy

Due to ever increasing traffic demands the fatigue safety and service life of the bridges of a railway line in Brazil need to be examined. Conventional assessment methods using load models and approaches as suggested in codes lead to conservative results r ...

Christian Menn's recent bridge designs - Reducing structural elements to the simplest solution

Eugen Brühwiler

The conceptual designs by Christian Menn of four landmark bridges are presented: 1) a 350-m span cable-stayed bridge with jointless deck girder, 2) a cable-stayed bridge with a single “spindle-shaped” pylon, 3) a bridge with an arch reaching high above the ...

Structural implications of ultra-high performance fibre-reinforced concrete in bridge design

Ana Spasojevic

The present research represents a theoretical and experimental contribution to the understanding of the structural behaviour of elements made of ultra-high performance fibre-reinforced concrete (UHPFRC). UHPFRC is investigated as an advanced cementitious m ...

A probabilistic study of fatigue in post-weld treated tubular bridge structures

Scott Walbridge

In the design of tubular bridges, engineers have found the fatigue performance of the joints to be a critical aspect that may have a significant impact on the economic viability of these structures. In looking for ways of improving this performance, the us ...
