ubc 1976-document
is there a copy of the ubc 1976 available somewhere on the internet. thanks!
get the ubc 97 here:
i'm looking for the seismic equations used on that code..
ok
i have a copy of the '79, maybe the '76 in my archives.
are you loooking for v= zikcsw and it's linked equations?
k in table 23-i (0.67 thru 2.5 depending on structure)
cs <= .14
c = 1/(15 * sqrt t)
t = .05 hn / sqrt d
z = zone factor
zone 1 = 3/16
zone 2 = 3/8
zone 3 = .75
zone 1 = 1.0
d = structure dimension in direction of applied force
i = importance factor (1.0, 1.25 & 1.5)
s = 1.5 default value

the equations above are from the '79 code. i am looking for the '76, but the '73 is different -
v = zkcw, with c = .05 / cube root of t
basically the same k factors, but with a max of 3.0
only three z zones, .25, .5 and 1.0
so, i guess i better look for '76

1976 is the same as 1979.
basically, yes. no changes noted in the '79 for the equations used.

thanks...it is exactly what i'm looking for...
