Приведена инженерная методика расчета узлов «плита–колонна», учитывающая различные классы бетона по прочности в плите и колонне. Точность предложенных зависимостей оценена в ходе сопоставления с опытными данными других авторов, а также с результатами численного моделирования. Оценка показала удовлетворительную точность предложенной методики расчета.

The article presents an engineering methodology for calculating the slab-column joints, coupled with different strength grades of concrete in slab and column. The accuracy of the proposed formulas was assessed in comparison with experimental data of other authors, as well as with the results of numerical modeling. Evaluation showed satisfactory accuracy of the proposed methodology.
