Заранее организованные трещины качественно меняют характер деформирования конструкций. В изгибаемых элементах до двух и более раз уменьшаются прогибы, увеличивается время сопротивления действию длительной нагрузки.</p></abstract><trans-abstract xml:lang="en"><p>The paper is dealt with the study of deformations of precracked concrete and reinforced concrete structures such as slabs and beams, induced by short- and long-term loads. A study of preckracked structures allows creating new trends in concrete development. Preckracking modifies the structural behavior, namely: beam deflections decrease twice or higher, the period of the load resistance increases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>энергетическая теория</kwd><kwd>трещиностойкость</kwd><kwd>жесткость</kwd><kwd>деформации</kwd><kwd>заранее организованные трещины</kwd><kwd>energy theory</kwd><kwd>crack resistance</kwd><kwd>rigidity</kwd><kwd>deformation</kwd><kwd>preformed cracks</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">Митасов, В.М.
