Discontinuous mode shapes and missing z-rotation modes
Discontinuous mode shapes and missing z-rotation modes
(OP)
Hi all,
Attached is the mode shapes of my building. Why some of the normalized mode highly discontinuous (in the second figure where the value of z-rotation times 211111)? Also, when z-rotation times the regular eccentricity, the z rotation almost equal to zero. However, my building has two eccentric concrete cores. why lol? Thank you so much for your kindly help in advance. Have a good day :)
