Page 5 - For loads acting perpendicular to the grain, the margin between the edge toward which the bolt pressure is acting and the center of the bolt or bolts nearest this edge should be at least four times the bolt diameter. The margin at the opposite edge is relatively unimportant.
Page 146 - L,jD ratio and species group, taken from this table, is the safe working stress at that ratio for joints with metal splice plates. When wood splice plates are used, each one-half the thickness of the main timber, 80 percent of...
Page 144 - Select from table 27 the basic stre&s in compression perpendicular to the grain for the particular species of wood and reduce in accordance with the service condition if the joint is to be used in other than a dry, inside location. Call this stress Si. (2) Calculate the ratio of the length of bolt in the main member to the bolt diameter (L/D) . Select the percentage r of basic stress from table 29 for the appropriate L/D. (3) Select the diameter factor v for the appropriate size of bolt (p.
