modeling walls with staad
the wall has 2 different section, the lower one  is 2' thick supporting the upper one which is 1' thick.  the problem is that i try to have the wall face match each other so the lower wall will carry eccentric load from above.  how would you model this wall, what command in staad do you use ??
thank you..
check out our whitepaper library.
why do you need to model this by computer, working out the eccentricity and therefore stresses in the lower wall is very easy by hand!

to model the eccentric wall you may use a rigid horizontal element as shown below
        1
        1   > upper 1' wall ( element )
        1
        1
    -----   > rigid element ( high thickness to obtain
    1                          rigidity)
    1
    1
    1       > lower 2' wall ( element )

first thing to do when using staad to model structure is to check your indemnity insurance as you may well need it!!!
be careful.
may be you want to check the offset command in staad.  this allows you to move the axis of the connected

could you explain more how to model it??
i know offset command but i have no idea how to apply it to the wall.
