Seismic loading for freestanding wall
Seismic loading for freestanding wall
(OP)
Hey you guys;
It would appear that the seismic loading for freestanding walls on spread footings is aquired under "non Structural components" in the 2006 IBC. For this situation, how does z/h work?
Thanks,
Stu

So next I would tend to think this is a Non Building structure (Fp = 0.3SdsW). However, the formaula given for 'rigid structures' is for a structure with a period of 0.06s or less. A freestanding wall it liable to have a larger period than that.
I am ending up using the formula in section 12.11 for structural walls(Fp = 0.4SdsW). I would like to use the Nonstructural Components (Sect 13) with z = 0 which puts me back down to the minimum of Fp =0.3SdsW. The assertion of letting z=0 works for calculating the steel for attatching the wall to the foundation. For determining the forces for overturning and sliding of the monolithic element, I am unsure about letting z = 0.
I discussed this with the reviewer of the project and of course he was comfortable with the conservative value.
Thanks you guys, for your feedback. I have been picking up good information from this board.
