what is structural analysis

Structural analysis is a branch of solid mechanics that uses simplified models for solids like bars, beams, and shells for engineering decision making. Its main objective is to determine the effect of loads on physical structures and their deformations, internal forces, stresses, support reactions, velocity, accelerations, and stability. The results of the analysis are used to verify a structures fitness for use, often precluding physical tests. Structural analysis is thus a key part of the engineering design of structures. Structural analysis is particularly important for structural engineers to ensure they completely understand the load paths and the impacts the loads have on their engineering design. Structural analysis can either be performed during design, testing, or post-construction and will generally account for the materials used, geometry of the structure, and applied loads. There are various methods used to perform structural analysis, depending on the level of accuracy required by the engineer. Structural analysis is also a strategy used in reading to help readers take apart words to understand their overall meaning.
