Numerical-experimental identification of the elastic and damping properties in composite plates

Thomas Gmür, Alain Schorderet, Marco Matter, Joël Cugnoni

A novel method is presented for estimating the elastic and dissipative parameters of composite plates and shells through a mixed numerical-experimental identification procedure based on the natural frequencies, modal damping factors and mode shapes of the ...

Structural analysis of a composite bridge structure combining UHPFRC and prestressed concrete

Eugen Brühwiler, Hamid Sadouki, Cornelius Oesterlee

Reinforced concrete being the most applied construction material today performs very well in most applications but still lacks durability under severe environmental conditions. Especially existing structures built decades ago show degradation. Using Ultra- ...

Reinforced concrete bridges under increased railway traffic loads

Andrin Herwig

The aim of this thesis is to provide rational engineering methods for the fatigue safety examination of existing railway bridges. Increasing railway traffic loading and enhanced structural analysis allow for higher exploitation of the capacity of bridge el ...

Shear strength of reinforced concrete bridge deck slabs

Rui Vaz Rodrigues

Reinforced concrete bridge deck slabs without shear reinforcement can be subjected to concentrated or distributed loads of important magnitude. Under these loads their structural response is not always ductile. In particular under concentrated loads their ...

Adhesively bonded and translucent glass fiber reinforced polymer sandwich girders

Thomas Keller, Julia De Castro San Roman Fest, Martin Schollmayer

An experimental program has been carried out to investigate the structural behavior of adhesively bonded glass fiber reinforced polymer (GFRP) sandwich girders. The girders, conceivable for main spans up to 20 m, are composed of translucent double sandwich ...

Berücksichtigung von dynamischen Verkehrslasten beim Tragsicherheitsnachweis von Strassenbrücken

Hannes Ludescher

It has been known for more than 150 years that action effects in bridges due to traffic action are higher than it has to be expected for purely static loads. In the design of road bridges, this difference is considered by multiplying static traffic loads w ...

Onboard Measurements of Pressure and Strain Fluctuations in a Model of low Head Francis Turbine. Part 2 : Measurements and Preliminary Analysis Results

François Avellan, Mohamed Farhat, Michel Couston, Silvia Natal

In this second part of a 2 papers series, we present the analysis of “onboard” measurements on the runner of a Low Head Francis model and comparison with the same type of measurements on a similar prototype, as well as a comparison with numerical calculati ...

Towards structural dynamics in condensed chemical systems exploiting ultrafast time-resolved x-ray absorption spectroscopy

Majed Chergui, Philip Pattison, Melanie Saes

The authors present the case for exploiting time-resolved x-ray absorption to study structural dynamics in the liq. phase. With this aim in mind and considering the large differences between absorption coeffs. in the optical and the x-ray domains as well a ...
