The need for transportation of fluids is increasing in recent years, calling for more
complex analyses and design of the related facilities such as tanks, pumping stations, pipe
racks, etc. If these are located in a high seismicity area and over a weak soil profile, the
dynamic soil-structure-interaction gets even more difficult to deal with, considering the high
number of unknowns and time constraints in most projects. In this paper, detailed dynamic
analysis performed for the foundations of a pipe rack using finite difference software is
presented. The pipe rack rests on single or braced barrette foundations in a drain column-improved
soil profile. In each analysis, the variation of acceleration along the soil profile
and maximum moment and shear force values on the foundation elements are calculated.
The most critical section, from the dynamic point of view, is found as the braced barrette
foundations resting on the region where drain columns are 37 – 41 m long. Another
interesting aspect of the analyses is the variation in the barrette forces when their
orientations were altered by 90°. Analysis results show that the moment and shear forces for
the “old” transverse direction can be used in the longitudinal direction in the revised
orientation of the four-barrette group.
