Novel structural engineering methods and technologies are urgently needed to improve the performance of existing structures, such as bridges. Limited funding and ever increasing user demands challenge current technologies which are often invasive and not c ...
Fatigue safety verification of existing bridges that uses ‘‘re-calculation’’ based on codes, usually results in insufficient fatigue safety, triggering invasive interventions. Instead of “re-calculation”, Structural Health Monitoring (SHM) should be used f ...
The construction industry is the largest consumer of raw materials and most of the environmental impacts of structures are embodied into load-bearing systems [1]. Civil structures are usually designed to meet strength and deformation requirements to withst ...
Assessment of existing bridge structures for inherent safety level or for lifetime extension purposes is often more challenging than designing new ones. With increasing magnitude and frequency of axle loads, reinforced concrete bridge decks are susceptible ...
There is a significant need to examine precisely the conditions of concrete road bridges because of the increasing traffic and axle loads and the fact that most existing bridges were not designed with respect to fatigue. In-situ investigations are challeng ...
The case study of the fatigue safety examination of the 120 years old steel riveted bridge carrying a single railway track on two main girders is presented. The overall assessment according to the Swiss Standard SIA 269 for existing structures indicated su ...
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 ...
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 ...
‘Structural UHPFRC’ stands for Ultra-High Performance Fibre Reinforced Cementitious Composite material, that is, complemented by reinforcing steel bars forming a R-UHPFRC layer with the goal to enhance the resistance and durability of structural elements i ...
