Hi,
I am modelling a 12" thick mat with continuous 8"x15" deep upward concrete curb with wood shear walls on top around the perimeter. I have modelled shear walls with linear shears and concentrated moment at the center of the wall segments. I am getting the overstress areas right next tot he location where i applied a concentrated moments at plywood shear walls. It appears that a 27" deep beam should be more than adequate with standard #5@12" reinforcing without a problem. So i started looking at the 3d representation of the area and it appears that my curb isn't modelled properly. i specified it to be 8"x15", but i wonder if it should be specified as 8"x27" (12" of mat foundation and 15" of the curb).
I would appreciate any help on this.
Regards,
Alexander
