The first cast-on site application of UHPFRC in Switzerland took place for the rehabilitation and widening of the bridge over river La Morge in 2004. Since then, over the last 10 years, this technology spread successfully in Switzerland for bridges and bui ...
This paper presents the results of an experimental test series on the soil-structure-pavement interaction in the vicinity of the transition slab at the end of an integral bridge. The main function of transition slabs is to ease the transition between the b ...
Les ponts mixtes ont été largement utilisés en raison de leurs avantages économiques, constructifs et structuraux. Par ailleurs, le marché de la construction commence à tendre vers l’utilisation d’acier à haute résistance HSS. Ce genre d’acier séduit par s ...

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 ...

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 ...

Corrosion of rebar within reinforced concrete is a major problem for countries where salt is applied to roads for deicing. Concrete structures are periodically inspected in order to monitor possible damage caused by chloride-induced corrosion of the reinfo ...
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 ...
By reviewing some of the reinforced-concrete structures built in the early 20th century, this paper questions the geometrical aspects surrounding their design. It is well established that in the case of Robert Maillart’s designs, he relied on the logic of ...
In this work, we present the SmartBridge, a novel bridge section model equipped with actively controlled arrays of flaps aiming at mitigating wind-induced vibrations of long-span bridges. The active model, as well as its support structure, is described in ...
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 ...
