23. STEEL CONNECTIONS

Try these first

1. 1.

   What are the common types of high-strength bolts?

   Hint

   Think of the common types used in steel constructions.

2. 2.

   What is a bearing type connection?

   Hint

   Consider where the load is applied.

3. 3.

   What material is A325 bolt made from?

   • 1. Stainless Steel
   • 2. Heat-treated Medium Carbon Steel
   • 3. Alloy Steel

   Hint

   Think about the temperature treatment involved.

4. 4.

   True or False: A slip-critical connection transmits loads through shear.

   • True
   • False

   Hint

   Remember what distinguishes slip-critical from bearing type connections.

5. 5.

   A high-strength bolt is subjected to a tension load of 90 kips. If the tensile strength of the bolt is 120 ksi, what is the required tensile stress area (An)?

   Hint

   Use the formula connecting load and tensile strength.

6. 6.

   Discuss how environmental conditions can influence the selection of bolt types in coastal constructions.
