Abstract: The I. H. B. (Increamental Harmonic Balance) Method in association with receptancemethod was be used to analyze the steady dynamic response of structures with locally frictional joints. The main advantage of this method is that the linearstructure and frictional joints can be considered seperately. The computationcost is very low, while the Degrees of freedom related to frictional are muchfewer than that of a linear structure. A computer program was developed as a post processing subroutine, which can be connected with a general F. E. M program as SAP or ADINA.
