This paper presents an investigation of the influence of vehicle transverse in-lane position on bridge traffic load effects. To analyze the influence, both finite-element analysis and statistical analysis methods are used, and various technical aspects are ...
To date, there have been few reports of fatigue problems in medium-span reinforced or prestressed concrete road bridges, primarily due to the high ratio of the dead load to live load in such structures. Where fatigue problems have arisen, they have general ...
Road traffic loading is a highly variable process with a wide range of complex variables to consider. Consequently, various simplifying assumptions are required to efficiently model heavy traffic events for bridge safety verification, which reduce the accu ...
In recent years, monitoring has offered a viable complement or even alternative to traditional analytical safety verification approaches. However, there still remains a lack of guidance for the use of monitored data in safety verification work. Limited res ...
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 ...
Due to the important direct and indirect costs of the intervention, more detailed examination methods based on data as obtained from monitoring is suggested. This paper reports on an ongoing study to examine the fatigue safety of one standard bridge type, ...
As bridges form the keystone of transport networks, their safe operation with minimal maintenance closures is paramount for efficient operation. Yearly increases in the volume of heavy traffic mean a higher number of fatigue damaging load cycles. The study ...

The need to maximise the lifetime of existing road bridges necessitates clear and efficient tools for engineers to perform structural safety verifications based on monitored data. This study develops methodologies for ultimate limit safety (ULS) verificati ...
