This paper discusses an agent-based framework for improved bridge asset management. The framework comprises a geospatial representation of a network, a bridge performance deterioration model, and behavioural models of key stakeholders.Effective…

The current 2004 revision of AS 5100.7 provides guidance on bridge rating which is the comparison of one assessment loading or vehicle to a code design load. The assessment loading or vehicle can be either a former code design load or a specific…

Each year, the Queensland Department of Transport and Main Roads (TMR) receives thousands of requests to allow innovative vehicles, cranes and heavy load platforms to access Queensland&rsquo

In this paper a framework for assessing the robustness of existing reinforced concrete structures under corrosion is presented. Robustness is defined as a structural property related to the tolerance to damage and is measured by the mean performance…

Cast iron was extensively used in bridge piers in early metal bridges in Australia. These cast iron bridge piers have performed well against atmospheric corrosion. However, the portion immersed in water suffers from graphitic corrosion, a form of…

Fatigue design of new bridges in New Zealand must consider the future demands from increasing heavy freight volumes and higher productivity vehicles. The new vehicles are designed to carry more freight with fewer trips to offset the reduced…

New Zealand (NZ) has introduced High Productivity Motor Vehicles (HPMV’s) to improve freight efficiency on its road network. The significant increase in vehicle mass limits has required a national bridge load capacity evaluation and strengthening…

Roads and Maritime Services of Transport for NSW in collaboration with the Bridge Solution Alliance formed by Freyssinet, Lend Lease and Sage Automation undertook a major maintenance project to solve stay cable vibrations, strengthening-related…

All road authorities have a range of bridges of varying ages and design classes, which have transitioned over time to carry modern heavy vehicles. This paper reports the structural assessment procedures adopted by the Queensland Department of…

The Queensland Department of Transport and Main Roads (TMR) commenced a program to theoretically assess the capacities of existing bridges on the freight network in order to develop a family of assessment ratios to facilitate rapid bridge…
