RE: Seismic design of block fences

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Bill,

Sorry, I was asleep at the switch when this one came through.  I'll put on
my TS13 "Nonbuilding Structures" Chairman hat.

We have discussed this in our committee and we will be pulling this into
"nonbuilding structures" eventually, and hopefully we will be able to add a
little clarity.  This has not been done yet.

Currently you are in the right spot (32-2).  The h sub x and h sub r is
intended to reflect the effect of elevated floors for nonstructural
components.  The intent is that when you are on grade, the h sub x over h
sub r term goes to 0.

O.K., got no responses on block fences.

Any opinion if I use Eqn 34-2:

V=0.56CaI*W
