Masonry design for siesmic

(OP)
How do we determine that a reinforced masonry wall has nominal ductility? This is in order to determine the force modification factor "R", for seismic design.

Your input is highly appreciated.


RE: Masonry design for siesmic

masonry is known to be brittle material, even if you reinforce it it is not recommended for sismic design, unless....... you wnat to use it

RE: Masonry design for siesmic

Yes in my case I have to use Masonry based on the Architects requirements.  The force modification factor "R" I was asking about is used in the NBC (Canadian code) for seismic design.  The code states values for R if the masonry wall has nominal ductility and other values for reinforced and unreinforced masonry walls.  So I wanted to know the definition of "nominal ductility" and how to determine this status.
