Evaluation And Seismically Isolated Substructure Redesign Of A Typical Multi-Span Pre-Stressed Concrete Girder Highway Bridge, Brian D. Richins
Evaluation And Seismically Isolated Substructure Redesign Of A Typical Multi-Span Pre-Stressed Concrete Girder Highway Bridge, Brian D. Richins
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Seismic considerations greatly influence the lateral and vertical design of a structure, often necessitating larger elements than would otherwise be required. Seismic isolation greatly reduces the demands on a structure due to earthquake loading, allowing the use of smaller, more efficient members and foundations. This case study illustrates the theory and procedure of evaluating the response of a recently built multi-span highway bridge using the most recent (2009) AASHTO code. Based on this response, an equivalent structure was designed to incorporate a seismic isolation system, and the substructure of the isolated bridge redesigned to meet the reduced demands more economically. …

Should a country export its mineral wealth in form of concentrates or should it locally treat its ores to produce metals as final products? In the past centuries pyrometallurgy was the only route to extract metals from ores and this required a large capital investment many countries could not afford to raise. This situation encouraged marketing of concentrates. Today, metallurgists have the option to use the hydrometallurgical route to process ores and concentrates at a reasonable capital investment. This opened the way to the possibility of processing ores locally. When need arises to increase production new units can be added …

This paper describes the preliminary design and energy analysis of a university research building in NSW, Australia. This case study highlights some of the challenges confronting those wishing to design cost-effective net zero energy buildings in the Australian higher education sector and beyond. The Sustainable Buildings Research Centre (SBRC) is presently under development at the University of Wollongong and will be a unique building in the local region and an exemplar in respect of demonstration of a range of technical and operational means of reducing greenhouse emissions and other ecological impacts. This paper provides details on the constraints and opportunities …

Research To Establish A Systematic Approach To Safe Welding Procedure Development Using Austenitic Filler Material For Fabrication Of High Strength Steel, Lenka Kuzmikova, John Norrish, Huijun Li, Mark Callaghan

High strength, thermo-mechanically treated steels often require very careful control of welding procedures to ensure freedom from hydrogen assisted cold cracking (HACC) in the weld metal and heat affected zone (HAZ) whilst avoiding undue loss of heat affected zone strength. In practice this leads to restricted operating envelopes and the requirement for rigorous procedure management. An alternative approach is the use of austenitic welding consumables but whilst this may be expected to expand the process parameter envelope its use is often restricted by adherence to procedures previously developed for ferritic consumables. The current paper describes the research undertaken to establish …
