Abstract

The study of structural dynamics focuses on a structure’s behaviour when it is subjected to dynamic loading. Dynamic analysis can be used to research dynamic displacements, time-history, and modal analysis. A static load is one that does not vary, whereas a dynamic load changes with time. If it changes slowly, the structure’s response may be determined with static analysis. However, if it varies quickly, the response must be determined with dynamic analysis. Dynamic analysis for simple structures can be carried out manually, but for complex structures, FEM can be applied to calculate the mode shapes and frequencies.
