1960's sbc live load
hi all,
does anyone have a copy of the sbc from the 60's or early 70's?  i am analyzing a balcony/gallery and it does not work for 60 psf live load.  i was trying determine if a smaller live load was required 35 years ago for a balcony.
any input would be appreciated!

i've got the 1976 edition of the sbc -
balconies and galleries - fixed seats - 60 psf
balconies and galleries - movable seats - 60 psf
exterior balconies - public - 60 psf
exterior balconies - private - 40 psf ***
footnote for *** says:  "exterior balconies, private, are those balconies for use by one or two families."
also it has:
theaters
    balconies - 50 psf
thanks jae,
we have the '76 sbc but i missed the theaters balconies 50 psf.  that must have been what the original engineers used.  unfortunately some of the members still fail. off to write a letter.
thanks again!
