Title: RE: QUESTION: Effective Length For Angle In Tension AND Compression
This is similar to axial forces in a stair stringer. What do you use for effective length of a stringer. I am guessing at this but, it would seem to me that you need not worry about effective length in a tension section. Therefore, how do you model the point where the tension and compression are zero. That point cannot really be modeled as a completely rigid connection or a completely pinned connection. I would probably model it as a connection that allows lateral translation but no rotation. Then if you use a pinned connection at the point of greatest compression, you would have a theoretical k-value of 2, which would basically put you back at using the full length as the effective length. Does this make any sense? I'm not sure - I wrestle with this myself.
