Book Description
Currently two different fatigue tests, the DABM test and the TR440 test, are being used in the cyclone prone areas to assess the fatigue susceptibility of roof claddings. This is because the recent TR440 test has not been accepted in the Northern Territory. In order to remedy this unacceptable situation, an extensive research programme was carried out at James Cook University to review the adequacy of these standard fatigue tests. This research programme involved wind tunnel investigations to develop a fatigue wind loading spectrum representing a design cyclone, and structural testing of roof claddings to simulated cyclonic wind forces and standard fatigue test loadings. The design cyclonic wind loading developed in the form of a matrix of number of wind loading cycles for various load levels was applied to roof claddings by a random block load testing method using a servo-controlled hydraulic testing machine in the structures laboratory. Two major groups of roofing profiles, namely the corrugated roofing and the trapezoidal roofing, were included in the investigation. Same roof claddings were also subjected to the standard TR440 test. This report describes the fatigue behaviour of roof claddings when they were subjected to the random block loading tests and the TR440 tests. A few excursions of loading during the random block load test was found to cause significant fatigue damage on corrugated roofing, but caused the reverse effect on trapezoidal roofing. The observation on corrugated roofing was attributed to the dimpling of crests at the fastener holes due to the few excursions of loading. The contrasting behaviour of trapezoidal roofing was due to the membrane action at the crests. Details on the contrasting behaviour, and all the test results are presented in the report. Comparison of the fatigue performance of roof cladding under random block load tests and TR440 tests was used to decide on the adequacy of the latter tests in simulating the cyclonic wind forces. It appeared that the TR440 test is unconservative for corrugated roofing profiles whereas it is conservative for trapezoidal profiles, mainly due to the contrasting behaviour. Fatigue behaviour of these roof claddings appears to be much more complicated than anticipated. Thus the task of assessing the adequacy of the standard fatigue tests or if necessary, developing a new fatigue test for all the cyclone prone areas, has become complicated. This report discusses the implications of this to the building industry, and suggests interim recommendations to resolve the current conflict over the duplicative fatigue testing.

Book Description
Design Transactions presents the outcome of new research to emerge from ‘Innochain’, a consortium of six leading European architectural and engineering-focused institutions and their industry partners. The book presents new advances in digital design tooling that challenge established building cultures and systems. It offers new sustainable and materially smart design solutions with a strong focus on changing the way the industry thinks, designs, and builds our physical environment. Divided into sections exploring communication, simulation and materialisation, Design Transactions explores digital and physical prototyping and testing that challenges the traditional linear construction methods of incremental refinement. This novel research investigates ‘the digital chain’ between phases as an opportunity for extended interdisciplinary design collaboration. The highly illustrated book features work from 15 early-stage researchers alongside chapters from world-leading industry collaborators and academics.

Book Description
Ecohouse is an exciting and timely text that tells you how to design low energy, environmentally friendly buildings today. It also provides the foundations for building design in a warming world, and stepping stones towards the zero-carbon emission buildings of tomorrow. Sue Roaf is famed for her approach to design and her awareness of energy efficiency. Here she reveals the concepts, structures and techniques that lie behind the realization of her ideals. By using her own house as a case-study Roaf guides the reader through the ideas for energy efficient design or 'eco design'. This guide to the ecohouse also explores 21 case-studies from around the world, from Norway and Sweden to India and Japan, Argentina and Mexico. Chapters by Christopher Day, Katerine Bohn and Andre Viljoen on ecological building materials and methods and a contribution by Robert and Brenda Vale - all experts in this field Ecohouse has a regularly updated companion web site providing further information on all issues relating to Ecohouse and eco design.
