Hi! I only need the solution for Fig. 9.7.

This is Problem 10.11 from textbook: Dynamics of Structures by Anil K. Chopra, fifth edition

(I don't care if you copy the solution manual because I cannot find it online for free! But if you do, please add some notes or insight into tricky steps please!)

Thanks in advance! :)

For the three-story shear buildings shown in Figs. P9.7 and P9.8: (a) Determine the natural vibration frequencies and modes, express the frequencies in terms of m, El, and h. Sketch the modes and identify the associated natural frequencies. (b) Verify that the modes satisfy the orthogonality properties. (c) Normalize each mode so that the modal mass Mn has unit value. Sketch these normalized modes. Compare these modes with those obtained in part (a) and comment on the differences. m/2 Rigid beams Pl EI EI 1m EI 1m El 2h Figure P9.7 For the three-story shear buildings shown in Figs.
