1.4.2. Beams

Try these first

1. 1.

   What is the primary function of a beam?

   Hint

   Think about what a beam does in a structure.

2. 2.

   Name a type of beam based on its support condition.

   Hint

   How many points of support does the beam have?

3. 3.

   What primary forces do beams resist?

   • Tension and compression
   • Shear forces and bending moments
   • Axial loads

   Hint

   Think about the forces acting perpendicular and parallel to the beam.

4. 4.

   True or False: All beams are simply supported.

   • True
   • False

   Hint

   Consider the different types of beam support.

5. 5.

   Design a reinforced concrete beam that can support a point load of 15 kN, considering a span of 4 meters and use normal strength concrete. Include detailed calculations.

   Hint

   Consider maximum moment calculations as well as beam shear capacity.

6. 6.

   Evaluate the impact of neglecting shear force calculations in a structure consisting of cantilever beams. What failures could occur?

   Hint

   Visualize a cantilever beam under load; think about where stress points are.
