ABSTRACT
This study extends the traditional problem of a seismic response of elastic foundations
under isothermal conditions when considering thermal effects. Firstly, a free-field model of
the elastic foundation is established under the incidence of plane P-waves. Then, utilizing the
principles of wave propagation in a homogeneous and isotropic thermoelasticmedium and the
principle of Helmholtz vector decomposition, the influence of thermal physical parameters
such as thermal conductivity, medium temperature on seismic ground motion of the free-
-field on elastic foundation is investigated, which provides a reasonable explanation for the
ground motion of a site under thermal effects.
