Modal Analysis

Plain Definition: An analysis method that breaks a structure’s dynamic response into individual vibration modes.

Technical Description: Solves the eigenvalue problem to find natural frequencies and mode shapes. Each mode represents an independent dynamic behavior.

Use in Design: Used in seismic analysis to determine how different parts of a structure respond to ground motion.
