6.1. Live Load Reduction

Try these first

1. 1.

   What is a live load?

   Hint

   Think about what people and furniture contribute.

2. 2.

   What does the K factor represent?

   Hint

   Consider how different beams and columns behave.

3. 3.

   What is typically reduced in large buildings due to unlikely simultaneous live loads?

   • Dead load
   • Safety margin
   • Live load

   Hint

   Consider the nature of usage across spaces.

4. 4.

   True or False: The K factor for corner columns is 2.

   • True
   • False

   Hint

   Recollect the specific values for structural elements.

5. 5.

   You have designed a recreational center with a large open space and several interior columns. How would you apply the live load reduction principle to different floor areas?

   Hint

   Consider how changes in space usage might affect load distribution.

6. 6.

   Given a roof with a total area of 700 ft², how would you calculate the reduced roof live load using the factors discussed? What are the limits in place?

   Hint

   Think about area thresholds for R calculations.
