Structural and Risk Assessment of Steel and Concrete Bridges using Inservice Dynamic Response
Mainmark are introducing the STRAAM system of full scale structural integrity assessment and continuous monitoring for Bridges into Australia and New Zealand. Advances in measuring extremely low amplitude vibrations combined with methods for…
Utilizing Compressible Inclusions and Cement Stabilised Sand for Integral Bridges
Bridges are designed to function for 100 years but often the costs of maintenance are very significant. Bearings and expansion joints which affect the performance of a bridge are mainly the source of maintenance cost. In this case, an integral…
Reliability-Based Increases to Capacity Reduction Factors for Australian Standards AS3600 and AS5100
Capacity reduction factors (?) for flexure, shear and axial loadings are derived for reinforced and prestressed concrete structures based on a reliability-based calibration of the Australian Concrete Structures Standard AS3600. The structural…
State-of-the-art Review on Strengthening Elements of Steel Bridges using CFRP
In the last few decades, the use of carbon fibre reinforced polymer (CFRP) for strengthening structures has attracted structural engineers due to its superior properties, such as its high strength-toweight ratio, corrosion resistance and ease of…
Chloride Ingress and Steel Corrosion in Slag and Fly Ash Blended Geopolymer Concrete
Alkali activated binders (geopolymer) is an emerging technology to produce concrete without the use of any Ordinary Portland Cement (OPC) by alkali activation of alumino-silicate source materials such as fly ash and/or slag. Limited knowledge on…
Strengthening-By-Stiffening: A New Concept for Strengthening Sheardeficient Thin-walled Steel Girders
Strengthening-By-Stiffening (SBS) is a new concept developed to enhance the strength and performance of shear-deficient thin-walled steel girders. In SBS, pultruded composite sections are bonded to buckling prone web panels to serve as stiffeners.
Corrugated Steel Culvert Lining Systems: Innovative Analysis and Design
Standard design techniques for corrugated steel culverts take advantage of the flexibility and ductility of the steel liners to transfer soil loads mainly through axial compression, with very small bending moments, relative to the size of the…
Thermal Response Analysis of Composite Steel Girder Bridges Subjected to Bushfires
The occurrence of fires on bridges usually has a low probability but it has a high impact on the economic and social aspects. However, bridge design codes and standards do not explicitly incorporate fire safety concepts in design stage which is in…
The Development of FRP Strengthening on the Victorian Road Network over the Last 17 Years
The global use of FRP (Fibre Reinforced Polymer) strengthening systems for bridge infrastructure has increased over the last 40 years, typically in North America, Europe and Japan. After a slow beginning, its
Improving Corrosion Resistance of Reinforced Concrete Structures Using Carbon Fibre Reinforced Polymer
Corrosion of steel is regarded as one of the most important issues for the durability of reinforced concrete (RC) structures, as corrosion can induce the serviceability decrease, bond strength dropping, steel properties reduction, and longitudinal…
