Q: The application of Castigliano's second theorem can be used to which type of structures?
  • A. For beams and frames only
  • B. For any type of Structure
  • C. Statically determinate structure only
  • D. Structures having point loads only
Correct Answer: Option B - Condition for validity of super-position principle– • Material should obey the Hook's law. • Structure is not subjected to any temperature change. • The structure is not analyzed for any support settlement. • The castigliano's theorem is valid only when super position principle is valid. • This theorem are applicable to any structure for which the force deformation relations are linear.
B. Condition for validity of super-position principle– • Material should obey the Hook's law. • Structure is not subjected to any temperature change. • The structure is not analyzed for any support settlement. • The castigliano's theorem is valid only when super position principle is valid. • This theorem are applicable to any structure for which the force deformation relations are linear.
