This example demonstrates how to perform eigenvalue analysis and plot mode shapes. Two-storey shear frame (Example 9.1a from "Dynamic of Structures" book by Professor Anil K. Chopra) is used for this purpose. Geometry and material characteristics of the frame structure are shown in Figure 1. Node and element numbering is given in Figure 2.
