It then develops a method for calculation of this response<br \/>\ntogether with the data required for its implementation. This method<br \/>\ntakes account also of the lateral response to buffeting by<br \/>\nacross-wind atmospheric turbulence components, using the methods of<br \/>\nESDU 89049<sup>5<\/sup>. Comparisons of predictions with both model<br \/>\nand full-scale measurements and a discussion of methods of reducing<br \/>\nthe response to vortex shedding are also included in ESDU<br \/>\n96030.<\/p>\n<p>The calculation method is complex and it can realistically be<br \/>\nimplemented only through a computer program. A program is currently<br \/>\navailable as a Microsoft Excel* spreadsheet Module.<\/p>\n<p>This Item gives guidance on the use of the Excel Module. Section<br \/>\n2 considers installation and running<sup>\u2020<\/sup> of the Module.<br \/>\nSection 3 describes the input data required and Section 4 the<br \/>\noutput produced by the program. Section 5 describes a set of Worked<br \/>\nExamples. Appendix A provides some guidance on values for input<br \/>\ndata.<\/p>\n<p>The method can be applied for the following structure types and<br \/>\nflow conditions:<\/p>\n<p>\u2022 parallel-sided, tapered and stepped structures,<\/p>\n<p>\u2022 circular or regular polygon cross section (8 or more<br \/>\nsides),<\/p>\n<p>\u2022 smooth or rough surfaces (for structures with ancillaries such<br \/>\nas ladders attached, the method applies only if the ancillary is<br \/>\nentirely within the main structure wake),<\/p>\n<p>\u2022 cantilevered structures and structures between end<br \/>\nfixings,<\/p>\n<p>\u2022 vertical, horizontal or inclined structures,<\/p>\n<p>\u2022 structures with or without strakes,<\/p>\n<p>\u2022 uniform or shear flow,<\/p>\n<p>\u2022 smooth or turbulent flow,<\/p>\n<p>\u2022 normal or yawed flow (a yawed wind affects the response only<br \/>\nif the structure is not vertical),<\/p>\n<p>\u2022\u00a0natural wind (full scale), simulated wind (wind<br \/>\ntunnel),<\/p>\n<p>\u2022 internal flows in which the structure causes a blockage of<br \/>\nless than 10%.<\/p>\n<p>Example applications include stacks (chimneys) and process plant<br \/>\ntowers, lighting standards and elements of lattice structures.<\/p>\n<p>Several worked examples are described in Section 5 and some<br \/>\nguidance on sources of input data is given in Appendix A.<\/p>\n<p>* Microsoft and Excel are trademarks of the Microsoft<br \/>\nCorporation<\/p>\n<p><sup>\u2020<\/sup> Some familiarity with the Microsoft Windows<br \/>\noperating system and the Microsoft Excel spreadsheet program is<br \/>\nassumed.
