Scenarios for determining strategies for traffic weight measurements in The Netherlands

Momenteel wordt informatie over het gewicht van het (vracht)verkeer op het Nederlandse wegennet verkregen uit 18 weegpunten in het hoofdwegennet, zogenaamde Weigh in Motion (WIM) systemen. Deze informatie wordt voor verschillende doeleinden gebruikt, waaronder toezicht en handhaving (door de Inspectie Leefomgeving en Transport (ILT), en het...

Information requirements for effective management of an ageing transport network

In this paper the budget prognosis and the technical end of service life issues of the transport infrastructure replacement program of Rijkswaterstaat are introduced. Furthermore the technical information required to execute the program in a cost-effective way while keeping the infrastructure safe and available is discussed. For fatigue and...

Strengthening of rivetedd connections of a steel Arch Bridge: Lessons learned

As part of an extensive renovation program, Arup Netherlands delivered engineering services for the strengthening and renovation of 8 large steel bridges in the Dutch highway network. Strengthening of the riveted splice connections at the ends of the hangers of a steel arch bridge on the Dutch A2 motorway represented a significant challenge to...

Validation of a crack growth model using observed cracks in a bridge

Fatigue life or crack growth predictions that use information from crack inspections have been applied to offshore structures and, in recent years, also to steel bridges. Apart from inspection data, a probabilistic crack growth model and knowledge of the distributions and correlations of the variables are required for such predictions. The...

Structural health monitoring in end-of-life prediction for steel bridges subjected to fatigue cracking

This paper presents a monitoring and modelling methodology to assess the current and future conditions of steel bridges subjected to fatigue cracking. Steel bridges are subjected to fatigue cracking as a result of fluctuating stresses caused by the crossing of heavy vehicles. Specifically for orthotropic steel bridge decks, fatigue cracking is...

Acoustic emission health monitoring of steel bridges

Despite extensive developments in the field of Acoustic Emission (AE) for monitoring fatigue cracks in steel structures, the implementation of AE systems for large-scale bridges is hindered by limitations associated with instrumentation costs and signal processing complexities. This paper sheds light on some of the most important challenges in...

Multidisciplinary health monitoring of a steel bridge deck structure

Fatigue cracks in orthotropic bridge decks are an important cause for the necessary renovation of existing bridges. Parallel utilization of various technologies based on different physical sensing principles can potentially maximize the efficiency of structural health monitoring (SHM) systems for these complex structures. A multidisciplinary SHM...

Structural health monitoring for fatigue life prediction of orthotropic bridge decks

Infrastructure asset owners are more and more confronted with structures reaching the end of their structural life. Structural Health Monitoring (SHM) systems should provide up-to-date information about the actual condition, as well predict the structural life and required maintenance of the assets for more cost effective and reliable operation...
