3. Design of Simply Supported Beams Using Rolled Steel Sections

Try these first

1. 1.

   Define a simply supported beam.

   Hint

   Think about how it behaves under loads.

2. 2.

   What does the term deflection refer to in beam design?

   Hint

   Consider how far a beam bends under weight.

3. 3.

   What is a simply supported beam?

   • A beam fixed at both ends
   • A beam with supports at both ends
   • A beam that cannot rotate

   Hint

   Think about how its supports behave.

4. 4.

   True or False: Dead loads are temporary loads that change over time.

   • True
   • False

   Hint

   Consider the nature of these loads.

5. 5.

   Design a simply supported beam with a span of 7 m. The total load is 20 kN/m, including dead and live loads. Calculate the required section modulus.

   Hint

   Review the formulas for bending moment and section modulus.

6. 6.

   Evaluate the deflection of a simply supported beam with a span of 6 m under a uniform load of 10 kN/m. Suggest ways to reduce the deflection.

   Hint

   Consider factors affecting deflection, like the moment of inertia.
