Free Standing Concrete Wall Seismic Design

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I think this may have been discussed previously but I could not find it.  I have a 14 foot high free standing concrete wall that looks like a typical retaining wall with 2 feet of soil on both sides (i.e. the wall sticks out 12 feet above grade).  The only purpose of the wall is to provide secondary containment if a large steel storm water tank inside the walled area fails (i.e. a once in life time event).  From a seismic standpoint (i.e. neglecting any water and assuming concrete dead load only) would the seismic loads from ASCE 7-05 be determined from Chapter 13 using Fp or from Chapter 15 using V.  If considering Chapter 13, I would assume an ap of 1.0 and an Rp of 2.5 for an exterior nonstructural cantilever wall.  If from Chapter 15, I would assume an R value of 3 for all other steel and reinforced concrete distributed mass cantilever structures.  Any comments?

Thanks,

Thomas Hunt, S.E.
