4. Design of Slab Base and Gusseted Base

Try these first

1. 1.

   What is a slab base?

   Hint

   Think about the type of loads it is designed for.

2. 2.

   Name one design consideration for a gusseted base.

   Hint

   Consider what additional elements are included.

3. 3.

   What type of base is suitable for moderate axial loads?

   • Slab Base
   • Gusseted Base
   • Both

   Hint

   Think about the strength requirements.

4. 4.

   True or False: Gusset plates are used only in slab bases.

   • True
   • False

   Hint

   Remember the different types of bases.

5. 5.

   You are tasked with designing a gusseted base for a steel column subjected to a vertical load of 750 kN. The concrete strength is 35 MPa. Calculate the required base plate area and discuss the design considerations for the gusset plates.

   Hint

   What should you account for regarding moment forces in your design?

6. 6.

   A building requires a slab base for a column with a maximum load of 300 kN. If the concrete strength is 25 MPa, determine the acceptable base plate thickness considering bending moments, and outline the design process.

   Hint

   What effect does load distribution have on plate thickness?
