The admissible deflection value has been exceeded for panel

[Victor_Huang1]

Hi All, 

I am modelling a panel retaining wall and got the admissible deflection value has been exceeded problem. 

Please find the model attached. 

Any idea how I can fix this problem?

Thanks.

Any help would be appreciated!!

Hello Victor.Huang,

What do you mean by "and got the admissible deflection value has been exceeded problem"

You have a horizontal (y) deformation of 4mm. if you calculate with cracked concrete maybe 10mm.

admissible l/250 = 5500mm/250 = 22mm. I dont see the problem?

Hi Dennisveendam

Thanks for the reply. 

I was trying to use the SLS design and the "error" kept on showing up.

See attached.

Hi Victor,

You use the Australian concrete code, I think you can ignore the warning and make the check for allowable deflection yourself as an engineer. A I can see it is not possible to give in a deflection limit in "shell & Plate reinforcement type". The SLS-tab is not present in the menu, see screens:

Code: AS3600

   

Code: EuroCode EC2

furthermore the design options/possibilities and checks in RSA for concrete walls with reinforcement are limited. 

If you go to "provided reinforcement" this message shows up.

Hi Den, 

Thanks for your help. 

In addition, any idea of how we can set to calculate the long term deflection?

Hello Victor,

You change the concrete E-modules, E-long term =  Eshort/3. Example C25/30 E = 28500Mpa Ecm = 9500Mpa, cracked/lond term:
