Question of the Day | 20-12-2020

For the frame loaded as shown above, which of the following is the most likely bending moment diagram due to the externally applied load?


  1. B is correct, as C and D needs a horizontal forece acting on the beam sections in order to have varying horizontal moments

  2. Option c…

    Conceptually if one was to visualize this problem as an inverted portal frame supported on 2 cantilever beams, the expected deformed shape would result in a moment distribution similar to option c. Mathematically, the moment diagrams should have gradients on the vertical segments and the horizontal segments near the support.
