The bolt group shown in Figure P consists of 3⁄4inchdiameter, Group A bearingtype bolts in single shear. Assuming that the bearing strength is adequate, use the tables in Part 7 of the Manual to determine: a. The maximum permissible factored load for LRFD. b. The maximum permissible service load for ASD.
A single-angle tension member, an L3 1⁄2 × 3 1⁄2 × 3⁄8, is connected to a gusset plate with 7⁄8-inch-diameter bolts as shown in the figure. A36 steel is used. Fy = 50 ksi, Fu = 58 ksi, E = 29000 ksi. Ag = 2.50 in^2. Assume that the effective net area is 85% of the computed net area.
The bracket connection shown in Figure must support an eccentric load consisting of 9 kips of dead load and 27 kips of live load. The connection was designed to have two vertical rows of four bolts, but one bolt was inadvertently omitted. If 7⁄8inchdiameter Group A bearingtype bolts are used, is the connection adequate? Assume that the bolt threads are in the plane of shear. Use A36 steel for the bracket, A992 steel for the W6 x 25, and perform the following analyses:
(a) elastic analysis,
(b) ultimate strength analysis.
