Аннотация
Актуальность. Представлено новое техническое решение швеллерных гнутозамкнутых профилей (ГЗП), выделяющихся составным сечением и относящихся к легким стальным тонкостенным конструкциям (ЛСТК), которые отличаются высокими технико-экономическими показателями и массовым спросом в промышленно-гражданском строительстве. Приведены также основные итоги сравнительного расчета оптимальных параметров гнутых швеллеров и швеллерных ГЗП на изгиб. Цель исследования - показать, что характеристики ЛСТК можно дополнительно улучшить при помощи формообразования модификации профилей, сочетающей в своем составном сечении прямые и круглые очертания замкнутых и открытых контуров. Методы. Посредством опытно-конструкторских проработок и оптимизационно-проектных расчетов швеллерных профилей разработано их новое техническое решение, оригинальность которого подтверждена патентной экспертизой. Результаты. Швеллерный ГЗП состоит из двух трубчатых полок и одной стенки двойной толщины. Для его изготовления без сварных, болтовых или заклепочных соединений наружная и внутренняя заготовки выполняются по всей длине с зубчатыми продольными кромками, зубцы которых расположены относительно друг друга в шахматном порядке и взаимно загнуты в пазах между собой после замыкания гнутого профиля по его полкам. Загибы зубчатых креплений увеличивают толщину смятия, обеспечивают рост местной устойчивости и прочности соединений тонкостенных элементов на сдвиг, а также позволяют не редуцировать расчетные сечения. Сравнительный расчет оптимальных параметров гнутых швеллеров и швеллерных ГЗП на изгиб показал, что у первых из них прочность максимальна при отношении габаритов ширины и высоты сечения 1/6, а у вторых - 1/5,68.
