Наибольшее распространение в современном строительстве получили круговые и параболические цилиндрические и конические поверхности, однополостные гиперболоиды вращения и гипары благодаря хорошо изученной геометрии их формы, существованию методов их расчета на прочность, устойчивость и динамику и их востребованности для практических нужд. Однако не прекращаются теоретические исследования и коноидальных оболочек, поиск возможностей их оптимального применения. Некоторые новые сведения по расчету прямых коноидальных оболочек на прочность, определению их частот собственных колебаний, знаковые примеры их применения для шедовых покрытий промышленных предприятий, для крыш частных вилл и общественных зданий, летних театров и музеев, в современных скульптурных комплексах приводятся в представленном обзоре. Показано, что в меньших масштабах, но продолжается проектирование и строительство коноидальных оболочек в 2000-2017 годах Вся основная приведенная библиография датируется XXI веком. </p></abstract><trans-abstract xml:lang="en"><p>Among tens of known ruled surfaces, which can be taken as middle surfaces of the shells, ruled surfaces of zero Gaussian curvature such as conic, cylindrical, and torse surfaces and also ruled surfaces of negative Gaussian curvature such as one-sheet hyperboloids, hypars, conoids find wide application. Circle and parabolic cylindrical and conic surfaces, hypars and one-sheet hyperboloid of revolution have the widest spread in modern design and building due to well-studied geometry of their form, existence of the methods of strength, buckling, and dynamic analyses, and due to their claiming for practical needs. But theoretical investigations of conoid shells, researches of their opportunities were not stopped. Some new information on strength analysis of right conoid shells, on the determination of their natural frequencies, examples of application of conoid shells for the shed roofs of industrial building, for the roofs of private villas and public buildings, summer theaters and museums, the application of them in modern sculptural complexes are presented in this review. It is shown that designing and building of conoidal shells is continued in 2000-2017 but on the lesser scales. All main presented references are dated the XXI st  century. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>линейчатая поверхность</kwd><kwd>коноид</kwd><kwd>цилиндроид</kwd><kwd>коноидальная оболочка</kwd><kwd>статический расчет</kwd><kwd>собственные колебания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ruled surface</kwd><kwd>conoid</kwd><kwd>cylindroid</kwd><kwd>conoidal shell</kwd><kwd>static strength analysis</kwd><kwd>natural frequencies</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Krivoshapko S.N., Ivanov V.N.
