ASCE 7-05 Section 12.2.5.5
(OP)
Folks,
Please see attached sketch.
I have a clerestory popup roof to which my concrete shear walls do not continue. I have a dicontinuous vertical system.
I need to use SMF because of my seismic design category. However, does Section 12.2.5.5 require me to continue it to the foundation even if I can adequately transfer the shear forces via the diaphragm to the concrete shear walls? This would be very costly to carry my moment frames all the way down just because they support a light roof.
Are there any ways to use the diaphragm to transfer the shear to the walls and carry it to the foundation without violating the code?
Thanks

Any clarification regarding code interpretation is much appreciated.

Again I am no expert on irregularities, but I think you have both vertical and horizontal irregularities.

I am just questioning the requirement for carrying a SMF all the way down to the foundation inlieu of transferring them to a shear wall.
I live in Miami and I don't do seismic design on a daily basis, and hence my question to the people who do this day in and day out.
Thanks
