A 5¹8 x 15 DF axial combination 5 glulam is used as the tension member in a large roof truss. A single row of 1-in. diameter bolts occurs at the net section of the member. Loads are a combination of dead and snow (ASD: D + S; LRFD: 1.2D + 1.6S). Joints are assumed to be pin-connected. MC = 10 percent. C₁ = 1.0. Find: a. The maximum axial tension load using ASD. b. Repeat part a except that the MC = 15 percent. c. Repeat part a except that the MC = 18 percent. d. Repeat part a except that the member is a bending combination 24 F-V8 DF glulam. e. The factored axial tension capacity using LRFD. f. Repeat part e except that the MC = 15 percent. g. Repeat part e except that the MC = 18 percent. h. Repeat part e except that the member is a bending combination 24F-V8 DF glulam.

Question
Transcribed Image Text:7.2 A5/g x 15 DF axial combination 5 glulam is used as the tension member in a large roof
truss. A single row of 1-in. diameter bolts occurs at the net section of the member. Loads
are a combination of dead and snow (ASD: D + S; LRFD: 1.2D + 1.6S). Joints are
assumed to be pin-connected. MC = 10 percent. C; = 1.0.
Find: a. The maximum axial tension load using ASD.
b. Repeat part a except that the MC = 15 percent.
c. Repeat part a except that the MC = 18 percent.
d. Repeat part a except that the member is a bending combination 24 F-V8 DF
glulam.
e. The factored axial tension capacity using LRFD.
f. Repeat part e except that the MC = 15 percent.
g. Repeat part e except that the MC = 18 percent.
h. Repeat part e except that the member is a bending combination 24F-V8 DF
glulam.
