Addressing the need to monitor concrete fatigue with Non Destructive Testing: results of Infrastar European project

Eugen Brühwiler, Imane Bayane

Fatigue is one of the most prevalent issues, which directly influences the service life expectancy of concrete structures. Fatigue has been investigated for years for steel structures. However, recent findings suggest that concrete structures may also be s ...

A GIS based approach for analysing geological and operation conditions influence on road tunnels degradation

Vincent Labiouse, Federica Sandrone

Adopting effective maintenance strategies for transportation infrastructures requires good prediction of their long-term behaviour. For planning interventions without affecting the entire network’s capacity, tunnels in particular require a good overview of ...

Post-tensioned glass beams

Jagoda Cupac

Over the last few decades, the application of glass in building construction has extended from small four-side supported windowpanes to areas traditionally reserved for other materials, such as roofs, floors, staircases and full building envelopes. Glass i ...

Studies of Sensor Data Interpretation for Asset Management of the Built Environment

Ian Smith

Sensing in the built environment has the potential to reduce asset management expenditure and contribute to extending useful service life. In the built environment, measurements are usually performed indirectly; effects are measured remote from their cause ...

Alkali-silica reaction: Current understanding of the reaction mechanisms and the knowledge gaps

Cyrille Dunant

Alkali-silica reaction (ASR) is a major concrete durability problem, resulting in significant maintenance and reconstruction costs to concrete infrastructures all over the world. Despite decades of study, the underlying chemical and physical reaction mecha ...

Static and fatigue strength of RC slabs under concentrated loads near linear supports

Aurelio Muttoni, Francisco Manuel Maciel Natário

RC slabs without shear reinforcement subjected to c oncentrated loads near lin ear supports are typical cases of deck slabs of bridges, transfer slabs or pile caps. Such elements are often designed or as sessed in shear with code provisions calibrated on ...

Fatigue Life Prediction of Adhesively-Bonded Fiber-Reinforced Polymer Structural Joints under Spectrum Loading Patterns

Roohollah Sarfaraz Khabbaz

New load-bearing structures made of fiber-reinforced polymer (FRP) composites comprise adhesively-bonded joints, which are components vulnerable to fatigue failure. These structural components are frequently subjected to complex cyclic loading histories ...

Specification and site control of the permeability of the cover concrete: the Swiss approach

Emmanuel Denarié

It is recognized that most damage to reinforced concrete structures is caused by insufficient durability rather than by low strength. In most cases, the quality and thickness of the cover concrete (covercrete) determine the service life of the structure. S ...

The Swiss experience on the wear of railway switches & crossings

Using databases of the Swiss Federal Railways (SBB CFF FFS), statistical analyses are carried out on the expected lifetime of railway switches (points) & crossings and their respective components. The expected lifetimes are attributed to different paramete ...

Towards more efficient structures with composite UHPFRC-concrete construction

Eugen Brühwiler, Emmanuel Denarié

The extremely low permeability of Ultra High Performance Fibre Reinforced Concretes (UHPFRC) associated to their outstanding mechanical properties make them especially suitable to locally "harden" reinforced concrete structures in critical zones subjected ...
