Structural Analysis is a method used in engineering and architecture to assess the stability and strength of structures. It involves evaluating how different forces, such as weight and environmental factors, affect a building or bridge. By understanding these forces, engineers can design safer and more efficient structures. The process typically includes mathematical calculations and simulations to predict how materials will behave under various conditions. Tools like Finite Element Analysis (FEA) are often employed to model complex structures. This ensures that the final design can withstand expected loads and stresses throughout its lifespan.
