The creation and development of the theory of creep of reinforced concrete is based on non-scientific principles take from systems of classical mechanics that do not correspond to this theory. A detailed analysis of the theory used in many countries was performed, while five oversimplifications were identified that reject fundamental experiments, Eurocodes, rules of mathematics and mechanics: listed in the law of creep, oversimplifications that grossly distort the calculation results, not only the deformations themselves, but also subsequent methods for calculating reinforced concrete structures. These include: unnecessarily modified classical Hooke’s law; imposing a property missing from concrete - an algebraic measure of creep; erroneous superposition principle; use of viscoelastic deformations instead of instantaneous nonlinear plastic deformations; replacement of obvious - nonlinear and non-stationary properties of concrete with linear ones, distorting the qualitative side of phenomena inherent only in nonlinear systems. These errors are covered by unreasonable safety factors, which undermines the economic component of the problem, and of the enormous volumes of reinforced concrete used throughout the world, the analyzed unscientific theory of its calculation causes enormous economic damage in global construction.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Исследованы важные особенности теории ползучести железобетона, выявленные и опубликованные ранее. В основе создания и развития теории ползучести железобетона заложены ненаучные принципы, заимствованные из несоответствующих этой теории систем классической механики. Проведен подробный анализ теории, применяемой во многих странах, при этом выявлено пять переупрощений, отвергающих фундаментальные эксперименты, Еврокоды, правила математики и механики: перечисленные в законе ползучести, переупрощений, грубо искажающих результаты расчета не только самих деформаций, но и последующие методы расчета железобетонных конструкций. К ним относятся: без надобности измененный классический закон Гука; навязывание отсутствующего у бетона свойства - алгебраической меры ползучести; ошибочный принцип наложения (он же принцип суперпозиции Больцмана); использование вместо мгновенных нелинейных пластических деформаций упруговязких деформаций; замена точных - нелинейных и нестационарных свойств бетона - линейными, искажающими качественную сторону явлений, присущих только нелинейным системам. Эти ошибки перекрываются необоснованными коэффициентами запаса, что подрывает экономическую составляющую проблемы, и ввиду громадных объемов применения железобетона во всем мире анализируемая ненаучная теория его расчета приносит значительный экономический ущерб в мировом строительстве.</p></trans-abstract><kwd-group xml:lang="en"><kwd>minute creep</kwd><kwd>creep measure</kwd><kwd>superposition principle</kwd><kwd>instantaneous elastic deformations</kwd><kwd>plastic hinge</kwd><kwd>long-term resistance of reinforced concrete</kwd><kwd>modern building codes</kwd><kwd>Eurocode principles</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>минутная ползучесть</kwd><kwd>мера ползучести</kwd><kwd>принцип наложения</kwd><kwd>мгновенные упругие деформации</kwd><kwd>пластический шарнир</kwd><kwd>длительное сопротивление железобетона</kwd><kwd>современные строительные нормы</kwd><kwd>принципы Еврокода</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Yu Q., Bazant Z.P., Wendner R.
