25.2. Example 25-2: T Beam; Moment Capacity II

Try these first

1. 1.

   What is a T beam?

   Hint

   Think about the shape of the cross-section.

2. 2.

   Define moment capacity.

   Hint

   Consider what happens when too much load is applied.

3. 3.

   What is the purpose of calculating moment capacity?

   • Determine the weight of the beam
   • Ensure structural safety
   • Calculate material costs

   Hint

   Think about why we design structures.

4. 4.

   True or False: A T beam is only used in small structures.

   • True
   • False

   Hint

   Consider the versatility of T beams in construction.

5. 5.

   Design a T beam to support a known load, ensuring to calculate the necessary reinforcement area and effective flange width.

   Hint

   Make sure to reference the ACI codes for the correct formulas.

6. 6.

   Evaluate how a 5% increase in width of the T beam flange would impact its moment capacity.

   Hint

   Think about load distribution as you adjust the dimensions.
