Modified Geometry of Transition Slabs for Integral Bridges

Over the past decades, an increasing number of integral bridges have been built. This type of bridge offers various advantages in comparison with standard bridges equipped with expansion joints and bearings. In particular, integral bridges require less mai ...

Influence of a Prestressing Eccentricity on the Punching Shear Strength of Post-Tensioned Slab Bridges

Aurelio Muttoni, Thibault Clément

A large number of medium and small span bridges in Switzerland and in other countries are slab bridges, often prestressed, multi-span and supported by columns. Punching in such structures is typically governing at failure. So far, the knowledge of the infl ...

Through-thickness performance of adhesive joints between FRP bridge decks and steel girders

Thomas Keller, Martin Schollmayer

The through-thickness performance of adhesive joints between pultruded FRP bridge decks and steel girders was investigated experimentally and numerically. Through- thickness tensile stresses occur due to uplift forces caused by the load-bearing behavior of ...

Dynamic amplification of traffic loads on road bridges

Eugen Brühwiler, Hannes Ludescher

Today all major standards implicitly or explicitly include an “impact factor”, “dynamic amplification factor” (DAF) or “dynamic load allowance”. The amount of dynamic traffic action represented by the factor varies considerably [6, 7]. The values are usual ...

Structuration of thin bridge and cantilever structures in thick-film technology using mineral sacrificial materials

Peter Ryser, Thomas Maeder, Caroline Jacq, Yannick Sébastien Fournier, Wassim Hraiz

Thick-film and LTCC (Low Temperature Cofired Ceramic) technologies find increasing use in meso-scale sensors, actuators and related devices that feature excellent dimensional, thermal and chemical stability at moderate cost. While several materials and pro ...

Through-thickness performance of adhesive connections between FRP bridge decks and steel main girders

Martin Schollmayer

FRP bridge decks offer several advantages compared with conventional concrete bridge decks, particularly their much lower weight, but also their resistance against corrosion as well as easier installation and maintenance. The poorly conceived methods avail ...

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 ...

Shear resistance of lightweight concrete core of FRP-concrete sandwich structure

Thomas Keller, Till Vallée, Erika Schaumann

This paper presents a model to predict the shear resistance of the unreinforced lightweight concrete core of a recently developed hybrid sandwich concept for bridge decks. The sandwich skins consist of a fiber-reinforced polymer (FRP) composite sheet for t ...

Modeling of through-thickness stress state in adhesive joints connecting pultruded FRP bridge decks and steel girders

Thomas Keller, Martin Schollmayer

The through-thickness performance of adhesive joints connecting pultruded FRP bridge decks and steel girders subjected to loading in the transverse bridge direction was investigated. Deck-to-girder adhesive joints can be assumed as being loaded by uplift f ...
