hello
i have wrote a cod for apply IDA on Simple Steel Framing with Reinforced Concrete Shear Wall(5,8 and12 story framing), my cod is correct and i have trace the ida curves. my max inter story drif for 8 story is almost .00013, i have no refrence for considering limit state particular for rc shear walls. is this drift common for this system type? is there any limit state for this structur system?
more information:
shear wall dime: 5story(5*.3m) 8story(5*.35m) 12story(5*.5m) boundary element hase same thickness.
i have use element dispBeamColumnInt .
far field records in ATC 63 for project.
use steel02 and concrete01.
opensees 2.1.
i have no limit state for my system.
can you help me?
tanks.

Dear Ali,

How do you model your wall? do you use shell element?

The problem with concrete walls is the luck of a suitable nDMaterial for the shells....

i have used fiber based element.
disp beamcolumnint for shear wall.
nonlinear beamcolumn for simple steel frame

check FEMA356 for limit states of concrete shear walls

Use the 'nodeDisp' command in your script

puts [expr ([nodeDisp $top 1]-[nodeDisp $bottom 1])/$H]
