ASTM Fasteners in Shear

Directions:

Solve each of the given problems. For each problem, list the given information and include all formulas where applicable, underline each answer, and be sure to label all data and number values where applicable. All work will be on engineering paper with the proper headings filled in on all sheets. The assignment will not be accepted if it is not on engineering paper. Include this assignment sheet along with your calculations on engineering paper for evaluation.

PROBLEM #1

What is the allowable load in kips for the following fasteners. Fasteners are in single shear. Use Table 7-1 (Available Shear Strength of Bolts, kips) in the AISC manual.

a.3/4" A325-N bolt (ASD)

b.1" A325-N bolt (ASD)

c.3/4" A307 bolt (ASD)

d.1" A307 bolt (ASD)

Problem #2

What is the allowable load in kips for the following fasteners. Fasteners are in double shear. Use Table 7-1 (Available Shear Strength of Bolts, kips) in the AISC manual.

a.3/4" A325-N bolt (ASD)

b.1" A325-N bolt (ASD)

c.3/4" A307 bolt (ASD)

d.1" A307 bolt (ASD)

Problem #3

What is the allowable load in kips for the following problems. Fasteners are in single shear. All fasteners are ASTM A307 bolts. Use Table 7-1 (Available Shear Strength of Bolts, kips) in the AISC manual.

b.9 rows, 7/8" (ASD)

c.6 rows, 3/4" (ASD)

d.2 rows, 3/4" (ASD)

Problem #4

What is the allowable load in kips for the following problems. Fasteners are in Double shear. All fasteners are ASTM A307 bolts. Use Table 7-1 (Available Shear Strength of Bolts, kips) in the AISC manual.

a.8 rows, 1" (ASD)

b.7 rows, 3/4" (ASD)

c.6 rows, 1" (ASD)

d.5 rows, 3/4" (ASD)

Problem #7

How many 3/4" diameter, ASTM A307 bolts are needed to support a load of 80 kips. Calculate for both single shear and double shear. UseASD values.

Problem #8

Using the data in the given figure, calculate the number of fasteners required to connect the two 5/16" angles to the gusset plate using 3/4" ASTM A325N bolts. UseASD values. (Note: bolts are in double shear.)

Problem #9

Using the data in the given figure, calculate the number of fasteners required to connect the two 5/16" angles to the gusset plate using 3/4" ASTM A307 bolts. UseASD values. (Note: bolts are in double shear.)

Problem #10

Using the data in the given figure, calculate the number of fasteners required to connect the gusset plate to the web of the channel using 7/8" ASTM A325N bolts. UseASD values. (Note: bolts are in single shear.)
