Modelling the influence of building types on the building response to railway vibration

摘要

A 2D BEM / FEM ground structure vibration interaction model is used to estimate the influence of building types on the building response to railway vibration. The results are expressed in terms of transfer function between free field ground vibration and building floor vibration. The ground / structure model is first experimentally validated from field measurements of ground and building vibration performed near railway and then used in a parametric study to evaluate the influence of floor thickness and span, as well as the thickness of buried walls and facades. Real railway ground signals are finally used to compare the results in terms of currently used vibration exposure indicators.
