Retaining wall

[MUHANNAD.ABU_ABDO]

how i can model the retaining wall by using RSA 2014 .. is someone give me an example ??

Very open question? 

Which part do you need to model?   Wall, footing, or both?  What conditions for support, what loads?

[MUHANNAD.ABU_ABDO]

i want both of them ( wall & footing ) .. also surcharge load , active pressure on stem and passive pressure on toe 

that's all ... thanks a lot 

[tony.ridley]

Have you made an attempt yet?

Show what you have tried.

It's a two way road.......

[MUHANNAD.ABU_ABDO]

okay i will 

[MUHANNAD.ABU_ABDO]

i tired to model it as solid .. i don't know if this is right or wrong .. 

[tony.ridley]

wouldn't do it with a solid.  Two plates will work . 

[MUHANNAD.ABU_ABDO]

can you show me how ?  and assign the load on it .. ! thanks sir 

[bjur]

I do it all the time. I'll upload a file Monday. Basically you model both wall and footing as panels. The footing panel has a horizontal planer reaction set along with soil reaction properties set. The loading on the wall is standard. The analysis is run as nonlinear due to the soil springs assigned to the footing.

oh great dear .. thanks a lot .. i'm waiting

oh that's great dear .. but if you can show me by video or photos to more accurate understanding 

[tony.ridley]

Why not just give your design parameters to Bjur, he can model it for you no? 

[MUHANNAD.ABU_ABDO]

i'm really want to know how can make this type of modeling .. i'm in problem i'm not joking .. if you want to help me i'm grateful to you

[saclovitzky]

why do you need to run it as non-linear analysis?Is the standard analysis not enough to capture the result?

[bjur]

Because the back of the wall footing may not have soil bearing (no tension on dirt). Need to run as nonlinear to remove reactions at any uplift areas.

Thanks Bjur, can you possibly look at my ret. wall model if it is done correctly(pls. see attached).
