Steel Buildings in Europe

Part 9: Design Software - Simple Connections 9 - 8 2 OPERATION OF THE WORKBOOK 2.1 Introduction worksheet The “introduction” sheet merely records the scope of the spreadsheet. On the initial loading of the workbook, this is the only worksheet tab visible. Choosing to “continue” reveals the remaining worksheet tabs. 2.2 Localisation worksheet The “localisation” sheet allows the user to select the language for the workbook and the National Annex (which determines the Nationally Determined Parameters (NDPs) that are to be used in calculations).. Checking the “overwrite” option allows the user to enter values of their choice. Deselecting this option leaves the National Annex selection as a blank – the user must select National Annex from the drop down menu. Default settings of Language and National Annex may be saved. The values are written to a simple text file, stored in the same folder as the workbook file. Subsequent saving will merely overwrite this file. Loading defaults will import whatever settings of language and National Annex that had previously been saved. 2.2.1 Material strength The steel design strength is taken from Table 3.1 of EN 1993-1-1, or the product Standard, according to the choice in the National Annex. Table 3.1 of EN 1993-1-1 covers material up to 80 mm thick. For thicknesses above 80 mm, the design strength is taken from the product Standard. 2.3 Input worksheet 2.3.1 Input information Basic selection of section type, section, grade of main member, plates and bolts is made on the "Input" sheet.
