Non-symmetrical punching of flat slabs and slab bridges without transverse reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar

Punching of flat slabs without transverse reinforcement has mostly been investigated in the past for slabs with equal reinforcement ratios in the two directions and loaded under axis-symmetrical conditions. However, in practice, slab bridges as well as man ...

Time domain simulation of soil-foundation-structure interaction in non-uniform soils

Matthias Preisig

Presented here is a numerical investigation of the influence of non-uniform soil conditions on a prototype concrete bridge with three bents (four span) where soil beneath bridge bents are varied between stiff sands and soft clay. A series of high-fidelity ...

Direct load transmission in hybrid FRP and lightweight concrete sandwich bridge deck

Thomas Keller, Till Vallée, Erika Schaumann

Direct load transmission experiments on hybrid short-span beam specimens for a novel bridge deck were performed. The sandwich construction consists of three layers: a fiber- reinforced polymer composite (FRP) sheet with T-upstands for the bottom skin, ligh ...

Consideration of dynamic traffic action effects on existing bridges at ultimate limit state

Eugen Brühwiler, Andrin Herwig

Dynamic energy due to ultimate limit state relevant traffic scenarios may completely be dissipated by plastic deformations without failure of the bridge element. If the structure shows significant strain hardening behaviour, the maximum static effect is al ...

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 ...

Concrete Cracking in Tension Members and Application to Deck Slabs of Bridges

Aurelio Muttoni, Miguel Fernández Ruiz

Currently, estimations of the crack width in the deck slab of bridges given by codes of practice are based on either theoretical or empirical approaches considering mainly the monotonic loading behaviour. However, cracking in reinforced tensile members is ...

In-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 ...

In-plane tensile performance of a cellular FRP bridge deck acting as top chord of continuous bridge girders

Thomas Keller, Martin Schollmayer

The in-plane tensile performance of a pultruded FRP bridge deck system was examined with regard to the use of the deck as the compositely acting top chord of hybrid bridge main girders in negative moment regions. The deck properties determined on the syste ...

Poinçonnement symétrique des dalles en béton armé

Stefano Guandalini

Punching of reinforced concrete and prestressed slabs is usually a critical failure mode for the design and verification of structures such as flat slabs or bridge slabs. Although codes of practice propose several rules for common cases (usually with an em ...
