Beam/ Column Behavior Due to Lateral Loads
Beam/ Column Behavior Due to Lateral Loads
(OP)
I was watching a video about Introduction to Earthquake Engineering and got stuck in this frame. If my memory serves me right, the moment resulting from that beam displacement would be clockwise and not counter clockwise as shown in the screenshot. Can anybody shed light on this for me. Thanks.

2) Earthquake or live lateral load diagram should not change depending on support at base.
3) If that's a completely rigid beam at the top, I would not consider it if determining loads at base supports (i.e. cantilever beam).
Note: I've found not to assume rigidity unless on short span lengths.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

But If I follow the diagram I encircled in the picture and draw the figure vertically, the moments drawn in the picture are CW. Is it wrong?
