Question

In the case of stiffness method of structural analysis, the quantity taken as redundant is

• A. Deflection or rotation
• B. Torsion
• C. Bending
• D. Strain energy

Hint:

Matrix methods: \[ \boxed{ \begin{aligned} \text{Force Method} &\rightarrow \text{Unknowns are Forces} \text{Stiffness Method} &\rightarrow \text{Unknowns are Displacements} \end{aligned} } \]

Answer 1

The Correct Option is A
