NCEES: Structural Sample problem 110

[Phatso86]

the answer is A if you assume K=1.0 for both spans

can anyone explain this to me?

thanks

The solution in the book (A) is correct. A length factor is not applied when determining moment distribution factors. Only a .75 when an end is pinned.

Is this only applicable to moment distributions?

If so, how do you know it is moment distributions that the question is talking about?

Lastly, why wouldn't end conditions affect the moment distribution?

If you perform a finite element anaylis, you'd get different value for moment all along the beam depending on fixed conditions.

or am i confusing this with something else?

thanks
