Question

A two hinged arch may be analysed using the following methods. (i) method of consistent deformation (ii) strain energy method (iii) column analogy method (iv) Kani's method

• A. (i), (ii) and (iii) are correct
• B. (i), (iii) and (iv) are correct
• C. (i), (ii) and (iv) are correct
• D. (ii), (iii) and (iv) are correct

Answer 1

Answer: (A)

It is indeterminate structure to the first degree. • It is not as rigid as fixed arches. • It may be statically made determinate by replacing one hinge with a roller. It is analyzed using the following methods– 1. Method of consistent deformation 2. Strain energy method 3. Column analogy method.
