1955 Roof Live Loads
1955 Roof Live Loads
(OP)
Anyone have any information as to what the UBC would have shown for required roof live loads back in 1955? Probably would be under the 1952 UBC...

On page 1-13 of the book it shows a map of the USA with the snow loads very similar to the snow maps in the IBC and ASCE 7-05 that is from the American Standards Building Code Requirements for Minimum Design Loads in Buildings and Other Structures, A58 1-1955 by the American Standards Association. Except that it is based on a 1 year in 10. But is does not have any snow loads for about half the western USA, mainly the mountain areas.
