3.3.3. Selection of Rolled Steel Section

Try these first

1. 1.

   Define what a simply supported beam is.

   Hint

   Think about its supports.

2. 2.

   What are the two primary types of loads in beam design?

   Hint

   Consider the loads acting on a beam's structure.

3. 3.

   What defines a simply supported beam?

   • Supported at one end
   • Supported at both ends
   • Pinned to the wall

   Hint

   Consider how many supports it has.

4. 4.

   True or False: The maximum shear force in a simply supported beam is applied at the midspan.

   • True
   • False

   Hint

   Where would you expect the greatest force?

5. 5.

   Evaluate a simply supported beam with a 5m span, experiencing a total uniform load of 20kN/m including self-weight. Calculate the required section modulus assuming permissible bending stress is 150 MPa.

   Hint

   Find the moment first, then use bending stress principles.

6. 6.

   Design a secondary beam in a floor system connecting to main beams. The beam spans 4m and supports a load of 8kN/m. Describe the necessary detailing connections.

   Hint

   Think about stability and load transfer capabilities.
