In the "Helps" said that combined wall is Overlapping or intersecting walls.But I want a straight combined wall to Design in RCDC
The wall are not combined in straight direction with the condition in "helps". I found that, the wall are combined after I add a beam at top of wall as a picture below.
The quations are..
1.Are there any other method to combined the straight wall?
2.Are there anyway to add the strut on top(as the picture below) that the wall are still combined?
(if there are addition node on beam at top of wall the wall aren't combined)
Hi,
Refer to the attached document for requirement of modelling a combined wall in RCDC.
For any more further clarifications, kindly get back to us.DOCX
Thanks for your response.If the wall are 40 meters of length, can I divided the wall every 5 meters and model the column in every 5 meters?
Second, exactly the model is a RC water tank then I want to put the strut(blue line in picture) between the wall. How to create it?
Water tank model that you need to create in STAAD and Design in RCDC has different modelling requirements.
You need to model the walls as Parametric surface and assign type walls, sub type - Tank walls.
Refer attached document which will help you understand the requirement of modelling a water tank in STAAD that can be imported to RCDC.
For further assistance, kindly get back.PDF
Parametric surface and assign type walls, sub type - Tank walls >> The design would be based on EN 02 - 2004 + EN 03 – 2006 UK code. But in my country prefer to use ACI318-2014 which is not support parametric surface type tank wall and tank slab.
So I have no choice to model tank wall design under ACI318 code except model the wall tank as combined wall. If you want more informations. please let's me know.
OK. It is not appropriate to design the Water tank wall as a regular shear wall in RCDC.
Currently in RCDC, Water tank Wall & Slab can be designed with EN 02 code. We will take the design of Water tank with ACI Code in our future release.
So, I want to know the different of model behavior between regular shear wall model and Water tank Wall&Slab model.
Are there any manual to explain this issue.
Thanks in Advance.
So, for identifying a shear wall in RCDC, one needs to model it as a 'Member' with the property of a wall.
For eg: If the cross sectional size of my wall is 300mm thk x 2000mm long, the I will model a rectangular member in RCDC and assign Yd = 2000mm & Zd = 300mm.
And while modelling a Tank wall or Tank slab - We need to model it as a parametric surface and assign the sub type as 'Tank Wall' or 'Tank Slab'. Refer attachment that explains the modelling requirement for a water tank structure.DOCX
