When computing the ultimate strength of rivets in shear, the following values in pounds per square inch of the cross-sectional area of the rivet shank shall be used:
PSIG | |
Iron rivets in single shear | 38,000 |
Iron rivets in double shear | 76,000 |
Steel rivets in single shear | 44,000 |
Steel rivets in double shear | 88,000 |
When the diameter of the rivet holes in the longitudinal joints of a boiler is not known, the diameter and cross-sectional area of rivets, after driving, may be selected from Table 1, or may be ascertained by cutting out one rivet in the body of the joint.
TABLE 1 - SIZES OF RIVETS BASED ON PLATE THICKNESS
Thickness of plate inches | 1/4 | 9/32 | 5/16 | 11/32 | 3/8 | 13/32 |
Diameter of rivet after driving inches | 11/16 | 11/16 | 3/4 | 3/4 | 13/16 | 13/16 |
Thickness of plate inches | 7/16 | 15/32 | 1/2 | 9/16 | 5/8 | |
Diameter of rivet after driving inches | 15/16 | 15/16 | 15/160 | 1-1/16 | 1-1/16 |
