Abstract

This paper is concerned with the dynamic response of truss structures containing linear- friction dampers. This type of passive energy dissipator shows different stiffness in loading and unloading, leading to triangular hysteresis loops under cyclic loading. The free and forced vibration responses of simple truss structures incorporating linear-friction dampers are analyzed. The harmonic linearization technique is used in combination with the modal strain energy method to estimate the response of truss structures with linear-friction dampers. The accuracy of this linearization technique is assessed in the context of truss structures in this paper. It is demonstrated that excellent accuracy is achieved using this linearization method.
