7.1. Truss types

Try these first

1. 1.

   What characterizes a Pratt truss?

   Hint

   Think about how the members are positioned.

2. 2.

   Which truss type is better for handling tension?

   Hint

   Consider how the diagonal members are oriented.

3. 3.

   What is a key characteristic of Pratt trusses?

   • A. Upward sloping diagonal members
   • B. Vertical and diagonal members
   • C. Rectangular frames

   Hint

   Recall the member positions.

4. 4.

   Vierendeel trusses primarily offer which benefit?

   • True
   • False

   Hint

   Think about how they differ from traditional trusses.

5. 5.

   Design a simple truss layout using both Pratt and Howe types to determine which aligns better for a mixed-use building.

   Hint

   Think about how each truss type performs under different load conditions.

6. 6.

   Calculate the optimal use of materials for an identical span using Warren and K trusses; determine cost-effectiveness.

   Hint

   Evaluate both design efficiency and life-cycle costs.
