Structural analysis with nonlinear behavior: The importance of going beyond the line

Resumo

This work discusses the importance of numerical methods in structural analysis. It deals specifically
with the analysis of frame structures where geometric and material nonlinearity is taken into account. The
importance of considering these effects is highlighted with examples of catastrophic events related to instability
phenomena. A computational program developed by the authors with educational purposes is presented and used
to perform the analysis of a simple frame.
