Abstract

Seventeen trusses, thirty-seven joints of structural frames, and three 15-ft struts, all of which had served for some 2½ years as structural parts of the Golden Gate International Exposition buildings at San Francisco, Calif., were removed from these buildings when they were dismantled, stored for some weeks in the open air, and later were tested for failure in a large testing frame constructed especially for this purpose. Also, one hundred and three laboratory specimens, constructed to find the lateral resistance of nails in plywood and the shearing and buckling strength of plywood panels, were tested. The trusses were of various types, spans, and sizes. Thirteen were entirely of timber. Seven of these had connections framed with split rings or shear plates, and the other six had connections of volts and washers.
