A mode shape is an instantaneous shape of a structure at a particular natural frequency. It is a deflection pattern related to a particular natural frequency. Each mode shape is associated with a specific natural frequency. It represents the relative displacement of all parts of a structure for that particular mode. Learn more about how to calculate mode shape of a structure analytically and numerically in detail in this video.
