Fatigue Damage Factor Calibration for Long-Span Cable-Stayed Bridge Decks

Alain Nussbaumer, José Joaquim Costa Branco de Oliveira Pedro, Cláudio Alexandre Pereira Baptista

Part 2 of the Eurocode 3 (EN 1993-2) proposes a straight forward fatigue verification method using a single heavy vehicle model (FLM3) and a damage equivalent factor, lambda, to represent the fatigue damaging effects of the real traffic on road bridges. Th ...

Behaviour of stiffened extended shear tab connections under gravity induced shear force

Dimitrios Lignos

Stiffened extended shear tab connections (either in full-depth or partial-depth configurations) are widely used to connect simply supported beams to the web of supporting girders or columns. Full-scale laboratory tests of stiffened extended shear tab conne ...

“Pocket-Monitoring” for the fatigue safety verification of bridge members in steel and reinforced concrete

Eugen Brühwiler

The fatigue safety of the reinforced concrete deck slab of a sixty-year-old steel-concrete road viaduct as well as the riveted steel girders of a 130 year old railway bridge was questioned based on the results of conventional assessment consisting in "re-c ...

Résistance au déversement des poutres métalliques de pont

Raphaël Thiébaud

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 ...

Structural performance of complex core systems for FRP-balsa composite sandwich bridge decks

Michael Osei-Antwi

Based on current fiber-reinforced polymer (FRP) composite construction principles, FRP decks fall into two categories: pultruded decks and sandwich decks. Sandwich decks comprise face sheets and either honeycombs or foams reinforced with internal FRP webs ...

Interaction between in-plane shear forces and transverse bending moments in concrete bridge webs

Aurelio Muttoni, Miguel Fernández Ruiz, Marie-Rose Backes

This paper investigates a reliable design approach for reinforced concrete panels subjected to the combined action of in-plane shear and out-of-plane bending moments, which develop in webs of boxgirder bridges and similar structures. Neglecting this intera ...

Prediction of fatigue life of reinforced concrete bridges using Fracture Mechanics

Eugen Brühwiler, Marina Rocha Pinto Portela Nunes

With the occurrence of higher and more frequent axle loads, bridges are more solicited by fatigue loading. Bridge elements like deck slabs are subjected to a high number of stress cycles at relatively small stress magnitudes. The application of Fracture Me ...
