5.2. Block Shear Failure

Try these first

1. 1.

   What is block shear failure?

   Hint

   Think about how a tension member reacts to forces.

2. 2.

   Name one factor that influences block shear failure.

   Hint

   Consider the importance of how members connect.

3. 3.

   What primarily causes block shear failure?

   • Improper welds
   • Excessive load causing tearing
   • Bending moments

   Hint

   Think about how too much tension affects a material.

4. 4.

   True or False: Block shear failure can only occur in steel structures.

   • True
   • False

   Hint

   Consider where connections are critical, not just steel.

5. 5.

   A tension member connects to a gusset plate with two bolts of 0.75 in. diameter through its 4 in. wide section. If the applied load is 5,000 pounds, calculate the net area for the tension member.

   Hint

   Remember to calculate the area of the bolts and subtract from the total area.

6. 6.

   Discuss how changing the material from A36 steel to A572 steel would impact block shear failure risk in a given member.

   Hint

   Consider differences in material strength and how they affect structural capacity.
