| Abstract: | Nonlinearity in structural analysis could be arised from material nonlinear effects and/or from kinematic nonlinear effects. The misunderstanding that they must be occuring simultaneously is definitely wrong. Typical examples are discussed to clarify the situation and to show what results would have occurcd if the proper analysis method were notchosen. Therefor, care should be taken to make proper judgement on the type of nonlinearity encountered in structural analysis. |
