Suppose that the units and accuracy are set to cm. In that case all rod lengths are presented in cm and up to 1 cm accuracy. In practice, bar lengths will be a multiple of 5 cm for example. Units and accuracy remain determined to cm.<\/p>\n

Select in the menu \u00abPreferences<\/strong>\u00bb the last command \u00abBar<\/strong> tolerances<\/strong> …\u00bb to make the length of the bars a multiple of 5 cm. The screen displays the following dialog:<\/p>\n

\"\"<\/p>\n

    \n
  • Enter in the dialog box the unit distance for the bar lengths and their distance to the nearest axis.<\/li>\n
  • Also enter the minimum intermediate length between two parts of a bar. Gaps smaller than the given value will not be cut out.<\/li>\n
  • Further on, the maximum deviation to theoretical required reinforcement section can be set. Either by a maximum absolute value or by a maximum relative value (percentage). This maximum deviation is only checked for values lower than the required value.
    \nSuppose that we need a theoretical reinforcement amount of 406 mm\u00b2. In practice, we would provide e.g. 2 bars \u00d8 16 (= 402 mm\u00b2). Strictly speaking, those 2 bars \u00d8 16 are insufficient. By setting a maximum deviation, we can force the program to accept it as sufficient.<\/li>\n
  • Also the minimum transverse distance can be set. Anyway, the program will always check that the centre-to-centre distance of bars is at least twice the diameter (net distance = diameter).<\/li>\n
  • Strictly speaking, it is not allowed that the support widths be less than the values that follow from the required anchorage lengths from the bars that are anchored in the support. Because this anchorage length is at the minimum 10 \u00d8, possibly reduced by a factor 2\/3 for direct supports, this means that bars \u00d8 25 can\u2019t be anchored on a support with a width of 19 cm. Since this, according to Eurocode 2 \u00abpractical\u00bb, rule in practice seems to be rather unpractical, ConCrete Plus allows you to just get a warning that the support should be wider, but the program will however generate the reinforcement drawing. Note that the acceptance of a smaller support width is not strictly allowed by Eurocode 2! Even more, these warnings can be eliminated by checking the checkbox, to avoid annoying messages that decreases the productivity.<\/li>\n<\/ul>\n

    With the button \u00abStore<\/strong>\u00bb\u00a0you can save the current input as default. With the button\u00a0\u00abRetrieve<\/strong>\u00bb\u00a0you can replace the current content of the dialog with the default values.\u00a0\u2013<\/p>\n<\/div>\n

    Stel dat eenheden en nauwkeurigheid ingesteld zijn op cm. In dat geval zullen alle staaflengtes voorgesteld worden in cm en tot op 1 cm nauwkeurig. In de praktijk zullen misschien eerder staaflengtes gebruikt worden die een veelvoud zijn van bijvoorbeeld 5 cm. Eenheden en nauwkeurigheid blijven echter bepaald op cm.<\/p>\n

    Selecteer in het menu \u00abVoorkeur<\/strong>\u00bb het voorlaatste commando \u00abStaaftoleranties\u2026<\/strong>\u00bb om de lengte van de staven een veelvoud te maken van 5 cm. Op het scherm verschijnt volgend dialoogvenster:<\/p>\n
