SkinnyBraces are precision engineered.  Your earthquake strengthening system needs to be engineered, too.

Design Professionals can use conventional design methods to determine the earthquake force that a SkinnyBrace must resist. The structural analysis can be based on the following:

Seismic Design parameters:

R = 6.5

Ω-nought = 3

C_d = 4 

Once the Design Professional determines the earthquake force, it is a simple matter to select a SkinnyBrace with suitable capacity. In rare cases, two or more SkinnyBraces may be needed along the same wall line.
