Question 1.
What is an axial load?
Show hintHide hint
Think about where the force is applied.
Question 2.
Name one typical steel section for columns.
Show hintHide hint
Remember the standards used for steel structures.
3Question 3.
What is the primary purpose of lacing in steel columns?
- To provide vertical support
- To connect column sections and ensure lateral stability
- To minimize weight in design
Show hintHide hint
Think about the function of connections in structure.
4Question 4.
True or False: A gusseted base is preferable when dealing with moderate axial loads.
- True
- False
Show hintHide hint
Consider the load capacities of different bases.
Question 5.
A structural engineer needs to design a steel column that will support a roof. The roof applies an axial load of 400 kN. The slenderness ratio of the column must be less than 180. If your selected section has a design compressive strength of 450 kN, is this section adequate? Justify your answer.
Show hintHide hint
Check the section properties to ensure it meets the height to width ratio.
Question 6.
Design a gusseted base for a column with an applied vertical load of 500 kN and a bending moment of 20 kNm. How would you calculate the required gusset plate thickness and spacing?
Show hintHide hint
Examine all forces acting on the base to guarantee stability.
