Multilevel Methodology of Numerical Seismic Analysis of Coupled Systems “Foundation - Shell - Pontoon (Floating Roof) -Column(s) - Fluid”

The distinctive paper is devoted to multilevel methodology of numerical seismic analysis of coupled systems “foundation - shell - pontoon (floating roof) - column(s) - fluid” (Methodology). It can be effectively used to help to ensure the safety of vertical cylindrical steel storage tanks for oil and petroleum products (hereinafter - tanks). Authors of Methodology have analyzed and taken into account of corresponding Russian design codes dealing with the safety of reservoirs, experience of design and analysis of reservoirs, international publications on issues of mathematical (computer) simulations of behavior of tanks.
