3.1. Types of Trusses

Try these first

1. 1.

   What type of load is the weight of the truss structure itself?

   Hint

   Think about permanent loads.

2. 2.

   Which method is used for analyzing trusses by focusing on the joints?

   Hint

   It deals with equilibrium at each connection.

3. 3.

   What is the primary function of a truss in roofing?

   • To increase aesthetic appeal
   • To support loads
   • To reduce costs

   Hint

   Think about what structural components do.

4. 4.

   True or False: The Method of Sections allows you to analyze trusses by cutting through members.

   • True
   • False

   Hint

   Consider the cutting method mentioned.

5. 5.

   Design a truss for a 10-meter span that will support a maximum live load of 2 kN/m² and a dead load of 1 kN/m². Choose an appropriate type of truss based on these loads.

   Hint

   Consider how the load impacts each part of the truss.

6. 6.

   Evaluate the effectiveness of using a Pratt versus a Howe truss for a roof with a high snow load. Discuss which would be more advantageous and why.

   Hint

   Focus on load direction and member strengths.
