High-value infrastructure elements, such as bridges, are typically over-designed. Model-updating techniques are useful for estimating the reserve load capacity (beyond safety factors) of bridges and this improves sustainability through good asset-managemen ...
As fatigue cracks were discovered under the bridge deck of the 48 years old railway bridge Linthkanal-Brücke, located near the Ziegelbrücke town in Switzerland, a few studies were conducted to understand the mechanism behind the cracks formation. However, ...
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 ...
"UHPFRC" stands for Ultra-High Performance Fibre Reinforced Cementitious Composite materials. UHPFRC - complemented with steel reinforcing bars - serves as an external reinforcement increasing the ultimate flexural and shear resistances as well as the fati ...
In this paper, although there are some useful monitoring methods for short and medium span(10-20m) bridges based on the qualitative or quantitative information, mainly two advanced structural health monitoring systems are described to review and analyses t ...
The science of adhesives and adhesion for structural connections has undergone significant development during the last few decades - and successfully so in a wide variety of industries. Recent applications of structural bonding are being adopted in the con ...
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 ...
The present invention relates to a micropile or tie (10) for connecting a structure (5) to a soil (2), the micropile or tie comprising: - at least one linear metallic element (11), - at least one external corrosion-protective duct (14), inside which is pos ...
The material UHPFRC is not yet used in the field of bridge construction regularly. The reasons are missing codes and allurements for innovation in the structural engineering. Nevertheless, UHPFRC has many advantages, which are significant compared to the u ...
Most civil infrastructure today was built during the second half of 20th century and is nearing the end of its service life. With increasing infrastructure demand that cannot be met with current resources for new supply, replacement of all aging infrastruc ...
