Does anyone have idea to solve this lateral load quesiton from Gang Chen book?

    Disclaimer: my response here is nothing more than my "gut" reaction and how I would answer this question if I got this on the exam and I, too, felt that I didn't have a grasp on this.  So - keep this in mind please, and I'd love to know what the actual answer is and anyone else's comments.

    My gut instinct is Column B because it is the only column that is braced on both sides.  If I had to imagine how this building would deform under lateral loads, it feels like to me that Column B would have the least amount of deflection because it is connected at both the top and the bottom, and, it is located in the middle of the building.

    Best guess - I welcome other responses, even if I'm totally wrong.  What does this book say is the correct answer?

    Column B would be my guess as well. Am curious to know the answer.

    Thanks for the try. Have you guys think of the column height and rigidity could relate to the lateral load each column would take?

    The answer is C. The reason is short column effect since column is shortest, it will take most lateral loads.
