Book Description
Global economic losses due to severe weather events have grown dramatically over the past two decades. A large proportion of these losses are due to severe wind storms such as tropical cyclones and tornadoes, which can cause destruction to buildings, houses, and other infrastructure over large areas. To address the growing losses, many new large-scale and full-scale laboratories have been developed. These tools are used to examine the issues that could not be solved with the traditional tools of wind engineering including model-scale boundary layer wind tunnels, simplified standardized product tests, and other methods of analysis. This book presents state-of-the-art results from the development of the many novel approaches being used to mitigate natural disasters around the world.

Book Description
Thin-plated structures are used extensively in building construction, automobile, aircraft, shipbuilding and other industries because of a number of favourable factors such as high strength-weight ratio, development of new materials and processes and the availability of efficient analytical methods. This class of structure is made by joining thin plates together at their edges and they rely for their rigidity and strength upon the tremendous stiffness and load-carrying capacity of the flat plates from which they are made. Many of the problems encountered in these structures arise because of the effects of local buckling. The knowledge of various facets of this phenomenon has increased dramatically since the 1960s. Problem areas which were hitherto either too complex for rigorous analysis or whose subtleties were not fully realized have in these years been subjected to intensive study. Great advances have been made in the areas of inelastic buckling. The growth in use of lightweight strong materials, such as fibre-reinforced plastics has also been a contributory factor towards the need for advances in the knowledge of the far post-buckling range. The conference is a sequel to the international conference organised by the University of Strathclyde in December 1996 and this international gathering will provide the opportunity for discussion of recent developments and trends in design of thin-walled structures.

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
ICSAS '99 - The Fourth International Conference on Steel and Aluminium Structures was a sequel to ICSAS '87 held in Cardiff, UK, to ICSAS '91 held in Singapore and to ICSAS '95 held in Istanbul, Turkey. The objective of the conference was to provide a forum for the discussion of recent findings and developments in the design and construction of various types of steel and aluminium structures.The conference was concerned with the analysis, modelling and design of light-weight or slender structures in which the primary material is structural steel, stainless or aluminium. The structural analysis papers presented at the conference cover both static and dynamic behaviour, instability behaviour and long-term behaviour under hygrothermal effects. The results of the latest research and development of some new structural products were also presented at the conference. A total of 76 papers and 30 posters were presented at the conference by participants from 36 countries in all 6 continents.
