This paper explores some specific features of seismic analysis of low-temperature tanks for storage of large amounts of liquefied gases under near-atmospheric pressure. Major construction types of this kind of tanks are composed of two vertical cylindrical containers with loose perlite insulation in between. The research is carried out to estimate the influence of the presence of loose isolation on a dynamic interaction between inner and outer vessels and stored liquid in case of a full tank and in case of an empty tank. It is concluded that the effects of this interaction can be neglected in case of a full tank and can’t be neglected in case of an empty tank.
