slender concrete shear wall analysis
hi all,
so, typically, i've seen engineers run etabs linear(elastic) dynamic analysis of concrete shear walls, with aci effective stiffnesses for cracked and uncracked sections.
on smaller buildings, i've seen engineers just run risa wall panels elements, discretized to get tensile forces for rebar.
but does anyone have other methods they would recommend?
anyone attempt to use sap?
but even with sap, that program does not capture slender wall buckling?  any thoughts?  i know the code had a lu/16 requirement at one point, but there are plenty of 30 ft warehouse walls that use 6" concrete panels?
what's the good word on slender walls?  (for in-plane forces)
thanks,

hey seattlemike;
    you want pca's "tilt-up load bearing walls".  almost by definition, tilt-ups are slender walls, and this work by kripanarayanan is a world-wide referenced authority for the design of tilt-up.  i think that would be an excellent reference for you, even if you do seem to be looking for a computer solution....
speaking of which, take a look at pca wall.  i haven't used it much, but i suspect it will do the job for you...
regards,
ys
