Hello everyone, as the thread title implies, I'm in a bit of a bind when it comes to understanding the Moment Distribution Method for displacement methods of analysis.(adsbygoogle = window.adsbygoogle || []).push({});

In particular, I am having a lot of trouble in determining Stiffness Factors. I have attempted to browse my book and online for clarification, but I feel like every source I look at contradicts the other.

For example...page two and page three of this pdf:

http://www.sut.ac.th/engineering/civil/courseonline/430332/pdf/04_MomentDistribution.pdf

It states that if the far end member is fixed, then the stiffness factor, K, is K=4EI/L. Okay.

But page 4 of this pdf then goes on to state that K(ab) = 3EI/L, even though the far end D on this is fixed.

Could someone please help me make sense of this? :(
