5. LRFD Design of Tension Members

Try these first

1. 1.

   What does LRFD stand for?

   Hint

   Think of it as a safety design principle.

2. 2.

   What is a tension member?

   Hint

   Think about cables or rods.

3. 3.

   What is the purpose of LRFD?

   • To minimize costs
   • To ensure safety in design
   • To enhance aesthetics

   Hint

   Think about why we use safety factors.

4. 4.

   True or False: Yielding in the gross section allows for dangerous elongation of the member.

   • True
   • False

   Hint

   Recall the effects of yielding.

5. 5.

   Given a tension member with a gross area of 12 in² and a yield stress of 40 ksi, determine the design strength based on yielding.

   Hint

   Make sure to apply the factors correctly.

6. 6.

   In a connection with an effective net area of 8 in² and a tensile strength of 75 ksi, if the connection lacks sufficient distance behind the pin, what could happen?

   Hint

   Consider the implications of tension on material structure.
