# Find spring constant of frame structure

I would like to calculate the spring constant of a frame structure. I thought that I could do it like this:

1. I apply a point force on the structure:

2. Then I calculate the displacement at that same point:

Finnaly, I asume that the material bends within its elastic limit: $k=\frac{F}{\delta_y}$

Question1: Do you agree with this method ?

Question2: If I have a different type of loading, for instance a distributed load, would the spring constant change ?
