3.3. Key Steps in Beam Design

Try these first

1. 1.

   What are the types of loads to consider in beam design?

   Hint

   Think about types of weights on a building.

2. 2.

   What does a simply supported beam mean?

   Hint

   Consider how a beam is placed between two supports.

3. 3.

   What is the formula for maximum bending moment in a simply supported beam under uniform load?

   • M = wL^2 / 8
   • M = wL^2 / 12
   • M = wL^3 / 3

   Hint

   Think about how moment calculations were performed.

4. 4.

   True or False: A simply supported beam is fixed at both ends.

   • True
   • False

   Hint

   Consider how the beam behaves under load.

5. 5.

   Design a beam to carry a total load of 12 kN/m over a span of 6 m. Calculate the bending moment, select a suitable section, and justify your selection.

   Hint

   Don’t forget to cross-check with provided section tables.

6. 6.

   A beam in a high-rise building has a loading scenario of 15 kN/m and spans 8 m. Analyze its design and propose lateral bracing measures.

   Hint

   Use actual design codes as guidelines for lateral bracing.
