15.2.2. Average Gross Dead Load in Buildings

Try these first

1. 1.

   What is a dead load?

   Hint

   Think of what makes up the static weight of a building.

2. 2.

   List two materials and their average weights.

   Hint

   Refer to the tables provided in the chapter.

3. 3.

   What does 'dead load' refer to in a building?

   • The temporary loads during construction
   • The permanent static weight of materials
   • Dynamic loads experienced during occupancy

   Hint

   Think of what remains constant over time.

4. 4.

   True or False: Dead loads only include the weight of floors.

   • True
   • False

   Hint

   Consider what other materials contribute to dead loads.

5. 5.

   A multi-story warehouse uses the following materials: steel framework, timber floors, and concrete roofing. Calculate the total dead load if the building has an area of 8000 ft². Steel weighs 70 lb/ft², timber weighs 50 lb/ft², and concrete weighs 150 lb/ft² respectively.

   Hint

   Use the weights and area to determine the total dead load.

6. 6.

   Discuss how the dead load would change if alternative materials with lower weights were used for the floors.

   Hint

   Consider the overall structural implications.
