crash wall footing

I'm designing a 2 column pier with a tall (15') wall.  How does RC pier treat the wall?  It looks like it does not deflect and I'm afraid that modeling it that way would be too conservative of a design for the columns.

    Please provide a screenshot of the pier with the wall so that we can better understand what exactly the situation is.

    Hi ,

    Please see the attached communities link which explains the design methodology of Crashwall.

    I attached a screen shot of the pier geometry to my other reply.
    I see the design method for the crash wall but not how they are getting the loads for the design. Also is it fixing the column at the top of the wall for the actual column design since it seems to be separating the 2 items (wall and column)? How does it handle the different stiffness between the columns and the wall and does the model really extend to the bottom of the footing?

    There is a brief explanation in the help file for the Substructure module of LBC, as shown in the screenshot below. Hope this clarifies.
