Try these first

1. 1.

   What is a dead load?

   Hint

   What kind of weight remains unchanged?

2. 2.

   List two materials and their weights.

   Hint

   What materials did we discuss earlier?

3. 3.

   What is the term for the total downward force generated by the weight of a building?

   • Live Load
   • Dead Load
   • Vertical Load

   Hint

   Think about which load is static.

4. 4.

   True or False: Reinforced concrete generally has a lower weight per square foot than timber.

   • True
   • False

   Consider the weight ranges we discussed.

5. 5.

   A classroom building has a floor area of 800 ft². It uses a concrete slab weighing 100 lb/ft² and tile flooring weighing 4 lb/ft². Calculate the total dead load and discuss the implications for structural design.

   Hint

   Don't forget to calculate the total load from each layer of flooring.

6. 6.

   Considering a building with a lightweight design, which materials from the section would you choose for a structure of 1,500 ft² and why?

   Hint

   Think about balancing weight with strength.
