Nonlinear structural analysis

Nonlinear structural analysis is a method used to predict how complex structures behave under various loads, especially when their response isn't straightforward. Unlike linear analysis, which assumes materials and structures respond proportionally to forces, nonlinear analysis considers factors like large deformations, material yielding, or complex boundary conditions that cause uneven or unpredictable responses. This approach provides more accurate assessments for advanced structures, ensuring safety and performance when dealing with real-world scenarios where linear assumptions don’t hold, such as during earthquakes, heavy loading, or structural modifications.
