Abstract
This paper deals with the experimental results obtained by in situ and model testing of a segment of
the pipeline system of a thermal power plant. The field testing has been performed by application of
the forced and ambient vibration method. The model testing has been performed by means of a
shaking table. The model was designed and constructed to the scale of 1/3 and tested on the seismic
shaking table in the IZIIS’ laboratory. The adopted modeling concept was: an adequate model with
artificial mass simulation, using the same material as that of the prototype. The spring hangings, as
well as the special rolling support have also been simulated. The model was subjected to random,
harmonic and earthquake motion in horizontal, vertical and biaxial direction. The results show that
the support springs can accept displacements in both horizontal and vertical direction in the elastic
range of deformation, while the stop point base support is sensitive to intensity of earthquake motion
and it is required to be limited in horizontal and vertical direction.
