Specific areas targeted for improvements are related to: a) Estimation of the loads exerted on anchored tanks, particularly the overturning moment, b) Estimation of the compressive stress and allowable shell buckling stress at the shell bottom.</abstract><trans-abstract xml:lang="ru">Статья содержит требования к расчету и проектированию вертикальных цилиндрических стальных резервуаров, эксплуатация которых предусматривается в сейсмически опасных районах и без установки анкеров. Сейсмостойкость резервуара обеспечивается при одновременном выполнении следующих условий: резервуар не опрокидывается при землетрясении; обеспечена устойчивость нижнего пояса стенки от действия продольно-поперечной нагрузки.</trans-abstract><kwd-group xml:lang="en"><kwd>Uplift</kwd><kwd>overturning</kwd><kwd>sloshing</kwd><kwd>cylindrical vertical steel tanks</kwd><kwd>seismic loading</kwd><kwd>simulation</kwd><kwd>elephant-foot</kwd><kwd>natural period</kwd><kwd>hydrodynamic pressure</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>подъем днища от основания</kwd><kwd>опрокидывающий момент</kwd><kwd>колебания жидкости</kwd><kwd>вертикальный стальной цилиндрический резервуар</kwd><kwd>сейсмические воздействия</kwd><kwd>моделирование</kwd><kwd>«слоновая ступня»</kwd><kwd>собственные частоты колебаний жидкости</kwd><kwd>гидродинамические давления</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Haroun M.A. Behavior of unanchored oil storage tanks: Imperial Valley Earthquake // Journal of Technical Topics in Civil Engineering.
