Structural analysis is the determination of the effects of loads on physical structures and their components. The structures subjected to this kind of analysis include all those that must withstand loads, such as buildings, bridges, among others. Structural analysis incorporates the fields of applied mechanics, materials science and applied mathematics, in order to calculate the deformation of the structure, as well as the internal forces, tension, support reactions, acceleration and stability. The results of the analysis are used to check the ability of a structure for its use, often without requiring physical testing. The structural analysis is, therefore, a fundamental part of engineering design of structures.
