2.1. Structural Elements

Try these first

1. 1.

   What are the two types of precast concrete beams?

   Hint

   Think about how they are reinforced.

2. 2.

   What role do columns play in a building's structure?

   Hint

   Consider what would happen if they were removed.

3. 3.

   What type of precast beam improves tensile strength?

   • Hollow Core Beam
   • RCC Beam
   • Prestressed Beam

   Hint

   Think about what prestressing means.

4. 4.

   True or False: Hollow core slabs have reinforced steel.

   • True
   • False

   Hint

   Consider what 'hollow core' implies.

5. 5.

   Design a floor plan for a small multi-floor building using solid slabs and precast staircases. Explain your design decisions related to material efficiency.

   Hint

   Focus on the balance between strength and weight.

6. 6.

   Evaluate a given scenario where a building underwent seismic forces. Discuss the implications for beam and column design.

   Hint

   Think about the engineering principles behind load resistance.
