Structural Dynamics is the study of how structures respond to dynamic loads, such as wind, earthquakes, and vibrations. It focuses on understanding the behavior of buildings, bridges, and other structures when subjected to forces that change over time. Engineers use this knowledge to design safer and more resilient structures. In this field, concepts like natural frequency, damping, and modal analysis are essential. Natural frequency refers to the rate at which a structure tends to oscillate, while damping describes how vibrations dissipate over time. Modal analysis helps engineers identify the different modes of vibration, ensuring structures can withstand dynamic forces effectively.
