Constructional method of UHPC on steel deck of long span suspension bridge and in-situ experimental test
The Second Dongting Lake (SDTL) Bridge is the longest steel truss girder suspension bridge in China, which has a main span of 1480 m. To alleviate deterioration issues in the orthotropic steel deck (OSD), the steel-ultra high performance concrete (UHPC) li ...
EPFL2020Résistance au déversement des poutres métalliques de pont
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 ...
EPFL2014Resistance to LTB of steel bridge girders
Jean-Paul Lebet, Raphaël Thiébaud
Lateral torsional buckling (LTB), a complex phenomenon of instability, occurs when a beam is solicited by a bending force. In the area of steel and composite bridges girders which are characterised by slender plate girders, few experimental and theoretical ...
ECCS European Convention for Constructional Steelwork2014Assessment of Shear Strength for Existing Bridges with Low Amounts of Shear Reinforcement
Aurelio Muttoni, Miguel Fernández Ruiz, Michael Markus Rupf
Design of concrete girder bridges has significantly evolved during the last decades. This has been particularly relevant with respect to shear design, motivated by changes in actions and design models. As a consequence, assessing the shear strength of exis ...
fib Symposium Tel-Aviv 20132013A 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 ...
CRC Press/Balkema2012In-plane compression and shear performance of FRP bridge decks acting as top chord of bridge girders
Thomas Keller, Herbert Gürtler
This paper reports on the composite action developed between pultruded FRP bridge deck systems and the supporting main girders for road bridges. Presented are requirements that an FRP deck must satisfy in order to function as part of the upper chord of the ...
2006Ermüdungsverhalten von Stahlgussknoten in Brücken aus Stahlhohlprofilen
Due to their aesthetic and structural advantages, tubular space truss structures are enjoying increasing popularity in modern bridge construction. The use of cast steel nodes for the joints between the circular hollow section members is also becoming incre ...
