Correct Answer - Option 3 : Slope deflection method
Concept:
Displacement method of analysis:
Primary unknowns are the displacements and initially, force-displacement relations are computed and subsequently, equations are written satisfying the equilibrium conditions of the structure in this method. After determining the unknown displacements, the other forces are calculated satisfying the compatibility conditions and force-displacement relations.
Different types of displacement method:
- Slope deflection method
- Moment distribution method
- Kani’s method
- Stiffness matrix method
- Castigliano’s Theorem- I
Force method of analysis:
The primary unknown forces in the members and compatibility equations are written for displacement and rotations (which are calculated by force-displacement equations) in this method. Solving these equations, redundant forces are calculated. Once the redundant forces are calculated, the remaining reactions are evaluated by equations of equilibrium.
Different types of force method:
- Virtual work/Unit load method
-
Method of consistent deformation
- Three-moment theorem
- Column analogy method
- Elastic center method
- Castigliano’s theorem of minimum strain energy
- Maxwell-Mohr equation
