Многочисленные экспериментальные исследования показали, что в двускатных балках наклонные трещины образуются не только в приопорной зоне, но и в середине пролета непосредственно у конька даже при отсутствии поперечной силы.На основании выполненных натурных испытаний двускатных балок и численного моделирования построены эпюры касательных и поперечных напряжений. Полученные данные выявили различия в распределении напряжений в двускатных балках и балках с параллельными гранями. Особенности напряженно-деформированного состояния балок ломаного очертания связаны с возникновением касательных напряжений от действия изгибающего момента и продольной силы из-за переменной высоты сечения элемента, а также с формированием локальных полей напряжений в зонах вблизи переломов граней.Предложенные аналитические зависимости позволяют вычислить касательные и поперечные напряжения в коньковой зоне двускатных балок и определить момент возникновения наклонных трещин в указанной зоне.</p></abstract><trans-abstract xml:lang="en"><p>Despite the widespread use of tapered beams, the features of their stress-strain state remain poorly understood, including in regions near curvatures of the faces.A lot of experimental studies have shown that in tapered beams, shear cracks occurs not only in the support zone, but also in the middle of the span directly at the apex, even without shear force.Based on the full-scale tests of tapered beams and finite element analyses, diagrams of shear and transverse stresses are constructed. The data obtained revealed differences in the stress distribution in tapered and linear beams. The features of the stress-strain state of the tapered beams are associated with the occurrence of shear stresses from the action of the bending moment and longitudinal force due to the variable depth of the section of the element, as well as with the formation of local stress fields in areas near the curvatures of the faces.The proposed analytical dependences allow us to calculate shear and transverse stresses in the apex zone of tapered beams and determine the moment of occurrence of shear cracks in the specified zone.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>двускатная балка</kwd><kwd>касательные напряжения</kwd><kwd>трещиностойкость наклонных сечений</kwd><kwd>эпюра</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tapered beam</kwd><kwd>shear crack</kwd><kwd>reinforced concrete</kwd><kwd>variable depth</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">Малиновский В.Н., Кривицкий П.В., Матвеенко Н.В.
