Try these first

1. 1.

   What is a dead load?

   Hint

   Think about what makes up the structure itself.

2. 2.

   Name one type of lateral load.

   Hint

   Consider forces that act horizontally.

3. 3.

   What are the two main categories of loads acting on structures?

   • Static and Dynamic
   • Vertical and Lateral
   • Internal and External

   Hint

   Recall the two categories that discuss weight and forces.

4. 4.

   True or False: Secondary loads do not impact structural design.

   • True
   • False

   Hint

   Think about how temperature might affect a structure over time.

5. 5.

   Calculate the impact of a live load of 50 psf across a 20 ft by 30 ft roof area. What is the total load?

   Hint

   First, determine the area of the roof, then multiply by the live load.

6. 6.

   Discuss the importance of wind loads in the design of skyscrapers and how designers mitigate their effects.

   Hint

   Consider how the shape of buildings can reduce or direct wind forces.
