Dear Mark et al
The orginal poblem is with a wood framed structure sitting on a wood framed
structure with an open end. In the older codes we used a cantilevered
steel column at the open end to act as a frame. If we do it now we have to
double the seismic loads on the whole structure. This is not possible.
It is true you can perform a dynamic analysis, and thus mitigate the issues
created by the soft story, however how do you model a wood shear wall or
diaphragm in your SAP program.
