Multiple Run Steel Stairs

I don't think this can be achieved in one go, we need to break the entire stair model into three parts, a quarter turn stair, a half turn stair and the landing between them can be modelled separately.

Can you provide the height of each of the landings?

Hi Tathagata,

A slight correction please, the total stair height is actually 5800mm and each riser is 200mm high across. From the natural ground level, first landing height is 1000mm, second landing height is 2600mm, Third  landing height is 4200mm and Final landing height is 5800mm. Datagroup stair type is "S-G23-StairsSteelOpen+EdgeStringers"

IF you construct the stairs in three parts, is it possible to merge the "stringers" so they appear continous. 

i would really appreciate a very short video if you don't mind as this would really help me

i look forward to hearing from you

thanks for your help

The best I could come up with is to place multiple stairs as mentioned, and then for that one landing place an appropriate stair which you would then drop, delete the stair components leaving just the landing geometry.   You could re-group that as well.  Once positioned you should have something similar to what you've shown.  Of course, for reporting purposes they will be identified separately.  

Hi Steve,

Thanks for the tip and this is exactly how i have been constructing the stair so far. i will send you a snapshot of the stair model once its completed.

Meanwhile, i can seem to find a suitable profile/section (these are bolted 5mm thin bars) for the X bracing highlighted in the image below. Do you have any other ideas how i can model these bracing with AECOsim tools. Actually, i can model them generically as smart solids but i want to avoid this as need to be able to report on them in the datagroup explorer. Also, is it possible to add a custom section or profile?

any ideas? 

Hi Henry,

Are they simply rectangular sections?   If so, you should be able manually add the appropriate size: https://communities.bentley.com/products/building/building_analysis___design/w/building_analysis_and_design__wiki/27165/create-an-individual-concrete-beam-or-column

Ignore the concrete part.  

Hi Steve,

what i eventually did was to use multiple "straight run stairs" between the landings. The landings have been modeled independently using the "Place Floor slab" and "Place Steel Beam" which illustrates both the landings and their various support. 

Hi Steve,

for some reason i do not understand, the section name dialog does not pop up when input the new numbers and hit enter. At the moment, i have just used a default size to illustrate the bracing against my wish. Do you know what could be wrong?

Hi Henry,

It seems to be working OK here.   As mentioned in the wiki make sure you're not entering any other characters other than the "x" between numbers.   Also, did you select a Code (XML file) prior to entering the section name?  That is where it should be written to.

Hi Steve.....is it possible for you to send me a quick video demonstration just incase i am missing something?

Hi Henry,

Sure, see if this helps.

Hi Steve,

Goodstuff! i really appreciate your brief video demonstration. Meanwhile, when i apply this same steps for "uk/Rectangular Tubes" e.g 50x150x5, it doesn't apply the hollow thickness for the tube. Does it work for you?

Hi Henry,

Ah, I see.   I think inputting custom sizes only applies to solid rectangular and round sections.  That might explain it.

Question - do you have any plans to upgrade to CONNECT Edition?   The next update includes a number of structural enhancements, including the ability to add custom sections ala ProStructures.
