Abstract: | In this paper, the
semi-infinite foundation is divided into far and near domains, and they are simulated by
the super-parameter mapping dynamic infinite element and the ordinary finite element
respectively. A coupling element between the superstructure and ground is also suggested
where by a mathematical model of numerical analysis for that system is established, on the
basis of which the effect of the foundation far domain, the elastic modulus ratio between
the height and span of the structure and input patterns upon the dynamic properties of the
system is analysed and studied. Accordingly, the results show that the effect is apparent. |
