6.3.2. Load Combinations

Try these first

1. 1.

   What is the purpose of load factors in structural design?

   Hint

   Think about safety in the design.

2. 2.

   Define Load Combinations.

   Hint

   Consider what happens when multiple loads act on a structure.

3. 3.

   What are Load Combinations used for?

   • To combine costs
   • To safely calculate multiple loads
   • To average loads

   Hint

   Think about safety in structure design.

4. 4.

   True or False: All loads act at their maximum simultaneously.

   • True
   • False

   Hint

   Consider real-world conditions.

5. 5.

   A roof structure is subjected to a dead load of 5 kN/m², a live load of 3 kN/m², and a snow load of 2 kN/m². Calculate the total adjusted load using load factors of 1.2 for dead load, 1.6 for live load, and 1.5 for snow load.

   Hint

   Apply each load factor to its respective load.

6. 6.

   Design a structural element considering the load impacts from wind and seismic factors. Given a wind load of 1.5 kN/m² and a seismic load of 2.3 kN/m², how would you use different load factors for safety?

   Hint

   Think about how to prioritize safety while integrating loads.
