10.1.1. Analysis Methods of Statically Indeterminate Structures

Try these first

1. 1.

   What is a statically indeterminate structure?

   Hint

   Think about how equations relate to unknown forces.

2. 2.

   Name one advantage of statically indeterminate structures.

   Hint

   Consider safety features in architecture.

3. 3.

   What characteristic defines a statically indeterminate structure?

   • More unknowns than equations
   • Only vertical loads
   • Always fails under load

   Hint

   Consider the definition of indeterminate structures.

4. 4.

   True or False: Statically indeterminate structures cannot redistributive forces upon member failure.

   • True
   • False

   Hint

   Think about structural safety.

5. 5.

   A propped cantilever beam of length L is subjected to a central load. Using the flexibility method, derive the expression for deflection at midpoint B due to applied load P.

   Hint

   Incorporate Virtual Work principles.

6. 6.

   Given a cable-supported plate structure, calculate the forces in each cable when a load is applied to the plate. Assume material properties are known and focus on elastic behavior.

   Hint

   Analyze changes upon loading!
