Accelerated Evaluation of the Effectiveness of Supplementary Cementitious Materials to Suppress Damaging AAR Expansion in Concrete Structures

This report provides the results of testing of three potentially reactive aggregates by the accelerated mortar bar test (AMBT) and the concrete prism test (CPT).

The tests were conducted using reference mixes, which contained plain Portland cement as…

Revised Seismic Design Provisions in AS 5100.2
The seismic design provisions in AS 5100 have recently been revised to accord with AS 1170.4:2007. The revised provisions were mainly based on Austroads technical report AP-T200-12, titled Bridge Design Guidelines for Earthquakes .
Next Generation of Facilities for Testing and Inspection of Bridge
This paper studies the mechanical and Data Acquisition performance of a Robotic Transverse Profiler (RTP), designed and built in the partnership between with ARRB and Laboratory of Motion Generation and Analysis for pavement technology study. A…
Bridge-Vehicle Dynamic Interactions: Results from Recent Load Tests
As part of the National Asset Centre of Excellence (NACoE), the Queensland Department of Transport and Main Roads (TMR) with ARRB Group has embarked on a program of research investigating the dynamic interactions between bridges and vehicles. The…
Wigram-Magdala Link Bridge: Low-Damage Details For a More Efficient Seismic Design Philosophy
The aftermath of the Christchurch earthquake highlighted difficulties in the assessment and repair of damaged plastic hinge zones in conventional reinforced concrete structures. Particular issues are uncertainty in strain history, low-cycle fatigue,…
Thermal Movements of Tasman Bridge
Tasman Bridge crosses the Derwent River joining Hobart to its eastern suburbs. It was built in the early 1960’s and reflects design concepts of the time. It is articulated so that the main viaducts are restrained by the abutments, with very slender…
Lessons from Bridge Performance Due to Ground Damage in Earthquakes
Transportation routes are key lifelines for the community and it is important to learn from damage to bridges in earthquakes. Ground damage was a major contributor to the damage to bridges, in the recent Wenchuan earthquake (China, 2008), the…
Destructive Load Testing of Transversely Stressed Deck Unit Bridges
As part of the NACOE research project ‘Deck unit bridge deck analysis under live load’, a comprehensive load testing program has been conducted in Queensland to investigate the behaviour of transversely stressed precast prestressed concrete deck…
Orbital Loading in Modular Bridge Expansion Joints
Whilst the use of expansion joints is common practice in bridge construction, modular bridge expansion joints are designed to accommodate large longitudinal expansion and contraction movements of bridge superstructures. In addition to supporting…
