Local scouring is a leading cause of bridge collapses. To protect bridges against local scouring, different countermeasures have been proposed and tested in the literature. In this study, the performance of collars was evaluated for scour reduction at two ...
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 ...
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 ...
In this study, a geothermal energy deicing system for bridge deck using a pile heat exchanger was developed, and the performance of this system was investigated under the conditions of snowfall. The structural response of the bridge deck during the deicing ...
The Chillon viaducts, in service since 1969, are two parallel structures with a total length of 2.1km each and spans varying from 92 to 104 meters. This post-tensioned precast concrete structure was strengthened with UHPFRC (Ultra High Performance Fiber Re ...
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, ...
Aging bridges of the German federal road network often cannot be rehabilitated or replaced timely due to insufficient funding and complex regulations of building laws. Consequently, novel building materials and alternative solutions get the opportunity to ...
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 ...
Much of the post-war reinforced and prestressed concrete infrastructure in North America and Europe is reaching its design life and engineers are in need of tools that can be used to assess the shear behavior of these structures. The Compression Field Theo ...
Geothermal energy is heat energy generated and stored in the Earth. With the awareness of the society about environmental issues, geothermal power is developing worldwide. It is cost-effective, reliable, sustainable, and environmentally friendly but has hi ...
