This paper is concerned with the boundary integral equation formulation and its numerical implementation for steady-state vibration analysis of spatial frame structures in the context of small elastic deformation and small strain theory. First, the integral equation formulation and its method of solution are presented in detail for a single straight bar subjected to distributed axial load, bending and torsional loads. Then, these are applied to the analysis of three-dimensional frame structures by assembling the element stiffness matrix of each element into the global stiffness matrix of the whole structure to be analyzed. A new computer code is developed in this study, and is employed to compute the steady-state responses of some frame structures, where by the usefulness of the proposed analysis method is demonstrated.
