Объектом исследования является несущая способность нормальных сечений изгибаемых железобетонных конструкций, армированных в растянутой зоне высокопрочными углепластиковыми материалами. Целью исследования является аналитическое получение наиболее универсальной и точной зависимости для определения предельного изгибающего момента элементов, армированных в растянутой зоне углепластиковыми материалами, с учетом их исходного состояния до усиления при разрушении сжатой зоны бетона. Задачами исследования являются: аналитическое получение зависимости для высоты сжатой зоны бетона в сечении в предельном состоянии после усиления с учетом начального напряженного состояния; сравнение несущей способности, полученной с учетом представленных зависимостей, по зависимостям, принятым в действующих нормативных документах, а также по нелинейной деформационной модели.
