Struktuuurianalüüsi

Struktuuurianalüüsi, also known as structural analysis, is a discipline within engineering that deals with determining the effects of loads on physical structures and their components. It is a subdiscipline of mechanical engineering and civil engineering. The primary goal of structural analysis is to understand how a structure will behave under various conditions, such as static loads, dynamic loads, and environmental factors like temperature changes. This involves calculating internal forces, stresses, strains, and deformations within the structure.

The fundamental principles of structural analysis are based on the laws of physics, particularly mechanics, and often employ principles of statics and dynamics. Engineers use mathematical models to represent the structure and the applied loads. These models can range from simple hand calculations for basic elements to complex computer simulations using finite element analysis (FEA) for intricate designs. The results of the analysis are crucial for ensuring the safety, stability, and serviceability of structures, preventing catastrophic failures, and optimizing material usage for economic efficiency. Applications of structural analysis are widespread, including the design of buildings, bridges, aircraft, vehicles, and many other engineered systems.
