Two existing bridges located along the M80 Ring Road were upgraded as part of the M80 Upgrade between Sydney Road and Edgars Road. An additional lane was added to each carriageway without widening either bridge. Both bridges were constructed with…

This paper will explore the opportunity to adopt 'low damage' seismic design technology in bridge design. Low damage designs offer a resilient and sustainable design option that provides a step change in seismic performance. However, to date these…

Major Road Projects Victoria upgraded the M80 Ring Road between Sydney Road and Edgars Road by building new lanes in each direction, lengthening existing freeway ramps, and installing ramp metering technology, with braided ramps between the Hume…

In early 2000, PTA has identified 31 dangerous level crossings within the urban electrified network with 20 of these crossings located along the Armadale Line. In 2014 the PTA undertook an assessment of the crossings and produced a report entitled,…

Ductile behaviour of steel is an important characteristic that underpins structural steel design approach. Ductility of steel enables it to undergo plastic deformation under overload conditions which serves as a warning sign indicating that the…
