(a) SpI it-ring connection
FIGURE 8
The Specification requires a minimum edge distance of 2% in (69.85 mm). The edge
distance in the present instance is 33 A in (95.25 mm).
- Calculate the net area of member A
Apply the dimensions of the groove, which are recorded in the Specification. Referring to
Fig. Sb, gross area = 27.19 in^2 (175.430 cm^2 ). The projected area of the groove and bolt
hole = 4.5(1.00) + 0.813(2.625) = 6.63 in^2 (42.777 cm^2 ). The net area = 27.19 - 6.63 =
20.56 in^2 (132.7 cm^2 ).
- Calculate the stress at the net section; compare
with the allowable stress
The stress/= load/net area = 26,000/20.56 = 1260 lb/in^2 (8688 kPa). From the Specifica-
tion, the allowable stress is/allow = (%)(1700) = 1488 lb/in^2 (10,260 kPa). Also from the
Specification, f^w = 1650 lb/in^2 (11,377 kPa). The joint is therefore satisfactory in all re-
spects.
- Establish the connector spacing
Using the Specification, apply the recorded values without reduction because the connec-
tors are stressed almost to capacity. Thus, a = 1 in (177.8 mm) and b = 9 in (228.6 mm).
