In the present work, the application of BEM FEM coupling is proposed in order to perform modal analysis of frame structures on elastic foundation. The influence of the elasticity of the foundation on the modal response of the structure is highlighted and the feasibility of the method, that can be easily introduced into routinely structural codes used in practice, is presented. In the work, the use of the Boussinesque solution for elastic half-space loaded on its limit plane produces that simplified integral equation can be written. Some modal analysis of frame structures on elastic foundation are presented and discussed.

Abstract
In the present work, the application of BEM FEM coupling is proposed in order to perform modal analysis of frame structures on elastic foundation. The influence of the elasticity of the foundation on the modal response of the structure is highlighted and the feasibility of the method, that can be easily introduced into routinely structural codes used in practice, is presented. In the work, the use of the Boussinesque solution for elastic half-space loaded on its limit plane produces that simplified integral equation can be written. Some modal analysis of frame structures on elastic foundation are presented and discussed.File in questo prodotto:
