Description

For the purpose of verification of mathematical models of reinforced concrete deformation and strength, realized by Abaqus software system, a number of natural objectives on fracture analysis of concrete and reinforced concrete under the action of thermal and extreme loads is carried out experimentally and then solved numerically and verified. On the basis of performed full-scale tests and constructed algorithm for definition material deformation curve for studied concrete types computational dependencies of stresses on tensile and compression deformation are obtained. It is shown that the mathematical model of «Concrete damaged plasticity» allows to take into account the non-linear properties of reinforced concrete with sufficient accuracy

Abstract (Russian)

С целью верификации математических моделей деформирования и прочности железобетона, реализованных в программной системе Abaqus, выполнен экспериментально, а затем численно решен и верифицирован ряд натурных задач по анализу разрушения бетона и железобетона под действием тепловых и экстремальных нагрузок. На основе выполненных натурных испытаний и построенного алгоритма определения диаграммы деформирования материала для исследуемых типов бетона получены расчетные зависимости напряжений от деформаций при растяжении и сжатии. Показано, что математическая модель «Concrete damaged plasticity» позволяет с достаточной точностью учитывать нелинейные свойства железобетона
