(adsbygoogle = window.adsbygoogle || []).push({}); I have strayed from the template because I am querying a methodology, not an explicit case.

This is Civil Engineering - Matrix Flexibility Method.

Given "m" members and "n" nodes I can use this matrix to solve the basic member forces:

(sorry about the size I don't know how to scale)

As far as I understand this can be easily done when the system isone degree indeterminate. My problem lies in calculating the above when the degree of indeterminacy rises above 1.

Say, for example, I have a structure that is two degree indeterminate.Can I do the following?

i.e. Can I continue expanding that displacement matrix vertically or must I include both redundant support reactions in one equilibrium equation (the first picture)?

I understand that this is a very specific portion of matrix methods and it may not be too clear. If anyone has any ideas or thoughts it would be greatly appreciated.

Thanks in advance.
