Abstract
There are two major contributions which are described in this paper. Firstl y, a new graphical user interfaces (GUI) interpretation tool for the non-li near frequency response functions (FRF) is proposed, The tool is developed by pv-wave package to provide better ways and user friendly of displaying, interpreting and analysing of non-linear systems with significant non-linea r effects. Secondly, the application of this identification tool for fault detection, identifying in the civil engineering. To demonstrate the improved visualisation and interpretation of the multi-d imensional non-linear FRF and the application of the non-linear auto-regres sive moving average model with exogenous input (NARMAX) methodology, two en gineering applications have studied including a non-linear oscillator and f ault diagnosis in civil engineering structures. The results obtained have s hown that the interpretation of the higher-order FRF has been comprehensive ly studied and non-linear effects have been related back to the physical mo dels of the systems.
