# Stiffness and Flexibility Methods of Structural Analysis

By Sachin Singh|Updated : August 23rd, 2018

### Stiffness and Flexibility Method

#### Flexibility

The flexibility of a structure is defined as the displacement caused by a unit force

where, f = Flexibility, δ = Displacement

P = Force, θ = Rotation, M = Moment

#### Stiffness

The stiffness is defined as the force required to produce a unit displacement.

where, k = stiffness

From Maxwell Reciprocal Theorem

Where

#### Difference between Force Method and Displacement Method
