BA Stairs

rklaschka

This is my first serious look at the Stair tool in BA. I am using it in a UK/European environment.I have had a look at us ncs dataset because I expect that is more feature complete but I am now using the 08.11.05.54 UK Uniclass as my base point with the intention of tweaking our customised in house dataset once I have learnt how it fits together

I have a choice to model the stairs in a conventional way - there a 4 stair cases two of which go up 7 storeys with differing storey height and two that are between two floors, which will 

I am working on the basis that to set out and model the stairs would probablytake me 1-2 days and as such I should spend this time working out how the tool works so I can use it within our system - do people think this is realistic?

I am looking to get a better understanding of the configuration and control of the tool. So some questions:

  1. The documentation looks a bit incomplete. There is a lot to take in here and some complex and powerful controls which I am discovering by trial and error which is tough.
  2. I am making a steel stair, which I have been advised that the stringers should be 300x20mm flats. There are no flats in any of the libraries. How do I create a stair of this type?
  3. I am struggling to get continuous sectioned stringers (using 200x100 RHS) at the moment because the mitring geometry around the inside of a U-shaped square looks like it is a little deficient and it appears that the controls to adjust the run-in and run-out at landings aren't there at least at a key-in dimensional level. For any stair with stringers I think this is structurally preferable but from an Architectural perspective it is aesthetically very important. It looks to me that the tool should be able to embody these a characteristics with in it. This would be really useful as its one of those difficult geometry exercises that you need to plot out very time. You could add a resolve mitring toggle - that would give you a minimum landing depth.


More later no doubt.

    You will have to add a new steel member into your steel.xml file if you dont have one already. What i suggest you do is create a project related steel file and create it as part of the project data. Or just find a steel file that has a plate in it and copy it into your steel file.

    Have a look at the file StructuralShapesTemplate.xls in the Workspace/triforma/Dataset_usNCS/data      folder. It has all teh details you need to create your own Structural members.

    Could you explain how the structural shapes template works? Or point me at the relevant bit of the manuals?

    When you open up the spreadsheet there should be a Toolbox called "Triforma" that has 2 buttons on it. A save button and a save as steel xml file or some such.

    I think you pretty much just enter the shape sizes you require into the excell spreadsheet then use the macro button to save as an xml file then you can either set it up as one of your steel files or copy/paste the info into your own steel.xml file that you use.

    I have as yet to actually get this file to work for myself. I always find the VBA doesnt want to work for me. Other people say that this file really does work though. There must be some setting I dont have on that wont let me use this file properly. If you know the workings of Excell then you should be able to get it working.

     If the file doesnt work for you you'll just have to decifer the xml file format and enter it in manually (which is pretty much what I do...)

    Cheers

    Thanks Damon,

    I am also struggling to get this to function. Can somebody from Bentley elucidate? A step by step approach to getting this to work in Excel 2007 is what I need.

    The toolbox Damon has described does not appear for me. Also some indication of which are required fields in the shapes tabs would be handy too.

    Wow, I haven't worked with these tools in years! But since I've only upgraded to Office 2007 about a month ago I figured it was time to start digging in...  So, here's how you can use the StructuralShapesTemplate.xls file to generate a valid section XML file.

     

    1) Click on the Excel 'Office' button - the "orb" at the upper left - and then click on the Excel Options button at the bottom of the pop-up menu
    2) From the Popular category, under 'Top options for working with Excel', check the 'Show Developer tab in the Ribbon' option then click OK.
    3) Open the spreadsheet, then switch to the 'Developer' tab enabled above
    4) Click on the 'Macro Security' button and from the Trust Center dialog check "Enable all macros (not recommended, potentially dangerous code can run)"
    5) Add the desired values to each tab as needed
    6) Once complete, click on the Export button in the XML section (Developer tab)
    7) The XML file you've just created should load up in Structural

    I just tried a quick test using this process, and was able to place the sections I created.  Whether this is the "right" way I cannot say, but it seemed to work OK!
