When using RAM Concept to distribute seismic shears from elevated slab to concrete walls (and to review columns for deformation compatibility), how do I account for cracked section properties at the walls and columns?
Thank-you.
For columns there is a Bending Stiffness Factor that can be used to reduce the flexural stiffness of the columns.
For walls you would need to reduce the thickness or modify the material properties (Criteria - Materials).
