Question

Which of the following statements is true with regard to the flexibility method of analysis?

• A. The method is used only for manual analysis of indeterminate structures.
• B. The method is used for analysis of indeterminate structures with lesser degree of static indeterminacy.
• C. The method is used only for analysis of flexible structures.
• D. The method is used to analyze determinate structures.

Answer 1

The correct option is B The method is used for analysis of indeterminate structures with lesser degree of static indeterminacy.

Flexibility method is used when:
$D_k>D_s$
$D_k\to \text{Degree of kinematic indeterminacy}$
$D_s\to \text{Degree of static indeterminacy}$
