Рассматривается влияние начального изгиба и последующего разгиба арматурных стержней на механические характеристики стали.

Актуальность

Актуальность. Данная проблема актуальна в практике строительства монолитных железобетонных конструкций, т. к. при производстве работ часто возникают ситуации, в которых отдельные арматурные стержни каркасов получают начальный изгиб, и возникает вопрос о возможности их дальнейшего использования.

Цель исследования

Цель исследования. Определение возможности применения арматурных стержней с начальным изгибом и последующим разгибом для железобетонных конструкций при варьировании параметрами начального изгиба.

Результаты

Результаты. По результатам экспериментальных исследований приведен сравнительный анализ механических характеристик образцов арматурных стержней, испытанных на растяжение на разрывной машине при варьировании начального диаметра загиба. Результаты испытаний позволяют сделать вывод о возможности дальнейшего использования арматурных стержней, подверженных однократному изгибу и обратному разгибу без снижения прочностных характеристик стали.

The article studies the influence of bending and unbending of reinforcing bars on the mechanical properties of steel bars. This problem is relevant in the practice of constructing monolithic reinforced concrete structures, since reinforcing bars are often subjected to initial bending. The question arises about their further use. Based on the results obtained, a comparative analysis of the mechanical properties is presented for reinforcing bars after tensile strength testing with varying the initial bend diameter. According to this testing, it is possible to further use these reinforcing bars after single and reverse bending without reducing the strength properties of the steel.
