Exploratory Statistical Analysis of Gas Reticulation Main Failures (Melbourne, Australia)
Research Report No RR12, January 2009
Abstract:
This report details the results obtain from an exploratory statistical analysis into the factors which affect the failure of gas reticulation pipe networks. Special consideration is given to the influence of climate on failure.

Field Measurement of the Behaviour of an In-Service Gas Reticulation Pipe Buried in Reactive Soil (Fawkner, Vic)
Research Report No RR13, March 2009
Abstract:
This report details the field instrumentation of and in-service low pressure gas reticulation pipe buried in reactive soils. Details is given on site investigations, instrument calibration, the instrumentation process and the results obtained from the site to date.

A Generalised, Closed Form Effective Width Method
Research Report No RR14, March 2009
Abstract:
The report presents some final modifications to the element approach to the design of cold-formed steel structures – the effective width method. Modifications include design rules for partially stiffened elements under uniform compression and under stress gradient, the effects of imperfections and rotational restraint between adjoining elements in the section, the effects of neglecting corner areas and the effects of determining the stress gradient from the gross section such that iterations are not required to establish the effective section. The modernised, simplified, generalised and closed form effective width method is shown to be accurate and reliable when compared with a database of nearly 1000 compression or bending members. The report is a continuation of the work presented in Research Report 9 “A unified element and section design proposal for cold-formed steel design”, RR9, 2008.
The report contains a summary paper in Appendix A, which should be read first – sections 1 – 4 contain supplementary material. The finalised effective width method is presented in section 1, a summary of the comparison with the members database is provided in section 2, the full comparison with the database is provided in section 3, and the experiments on uniformly compressed channels are presented in section 4.
Keywords:
Cold-formed steel design, thin-walled structures, effective width method.

Aluminium-CFRP and Stainless steel-CFRP
SHS tube tests
Research Report No RR15, April 2009
Abstract:
In this report investigations of composite steel-CFRP SHS tubes are extended to composite stainless steel-CFRP and aluminium-CFRP SHS. Experiments of tubes with two different metal SHS geometries and two different matrix layouts of carbon fibres are described and compared with the steel-CFRP results.
