STUDY OF THE VIBRATIONAL POWER INJECTED TO A WALL EXCITED BY A GROUND SURFACE WAVE

The physical understanding of ground/structure vibrational interaction is essential in order to relate ground vibration levels outside buildings to structural vibration levels in buildings. A 2-D FEM/BEM computer program has been developed and is used to study the simple problem of surface excitation of a single wall and its foundation. It gives some understanding for the case of buildings parallel to nearby surface railway tracks.
