THE DYNAMIC ANALYSIS OF LIGHT ALUMINIUM/STEEL STRUCTURES SUBJECTED TO WIND EXCITATION

In recent years an expanding market for light skeletal structures such as walkways, shelters and large bus stations has required constructors and customers to seek information on their behaviour when subject to wind excitation. The design of structures, taking into consideration the criteria associated with the dynamic response to wind excitation, is a specialised and highly complex task. The most significant guide for designers available at present is that produced by ESDU International plc. This is, however, apparently limited to particular types of structures and requires considerable interpretation in its use. The paper reports on an examination of the dynamic response of light aluminium/steel structures, where the required dynamic analysis was carried out using the finite element method and long walkway shelters, upwards of 300 m, are a particular focus. Significant idealisation of the physical problem is established and the paper presents the "best" model for the analysis. The results of a parametric study are presented and combined with the wind excitation criteria, prescribed by ESDU, design curves are proposed. The finite element results are underpinned at this stage by more traditional methods of dynamic analysis, however, future experimental work is described to further validate results. The paper concludes on the validity of the finite element modelling of the light structures and the implications of the work on design methodology.
