Textbook Problem

The tension member is a PL

**a**. Check all spacing and edge-distance requirements.

**b**. Compute the nominal bearing strength of each bolt.

Expert Solution

To determine

**(a)**

If all the spacing and edge distance requirements are adequate.

The spacing and the edge distance provided are adequate.

**Given:**

Tension member is

Thickness of the gusset plate is

Diameter of the bolts is

Steel Used is

**Calculation:**

The properties for

The ultimate tensile stress is

Write the expression for minimum spacing.

Here, diameter of the bolt is

Substitute

The minimum spacing between the bolts is

For the edge distance to be adequate, the value of edge distance should be greater than or equal to the value of minimum edge distance.

Here, edge distance is

The value of edge distance is

**Conclusion:**

Thus, the spacing and the edge distance provided are adequate.

Expert Solution

To determine

**(b)**

The nominal bearing strength of each bolt.

The nominal bearing strength of the edge bolt is

**Calculation:**

Write the expression for nominal bearing strength of a bolt.

Here, the nominal bearing strength is

With the upper limit of nominal bearing strength of the bolt,

Write the expression to calculate the value of

Here, height of the bolt is

Write the expression to calculate the value of

Here, spacing between the bolts is

Write the expression to calculate the height of the bolt.

Calculate the value of

Substitute

Calculate the value of

Substitute

Calculate the nominal bearing strength for edge bolts.

Substitute

Calculate the upper limit of nominal bearing strength for edge bolts.

Substitute

Thus, the minimum value of

Calculate the value of

Substitute

Calculate the nominal bearing strength for inner bolts.

Substitute

Calculate the upper limit of nominal bearing strength for inner bolts.

Substitute

Thus, the minimum value of

**Conclusion:**

Thus, the nominal bearing strength of the edge bolt is
