Цель исследования. Целью данного исследования является анализ конструктивных возможностей и ограничений применения текстильно-армированного бетона (ТАБ) в кровельных системах спортивных сооружений, с особым вниманием к консольной конструкции крыши стадиона, адаптированной под климатические условия Сочи.

Методы

Методы. В исследовании используется расчетная модель консольной кровельной конструкции, выполненной из ТАБ, с геометрией консольного выноса 22,735 м и общей шириной 84,4 м. Для анализа применяются численные методы с использованием конечно-элементной модели в ANSYS. Рассматриваются нагрузки, включая снеговые и ветровые, с соответствующими нормативами для Сочи. В ходе расчётов исследуются различные варианты толщины покрытия и длины консольного выноса.

Результаты

Результаты. Результаты расчётов показывают, что применение ТАБ значительно улучшает жесткость конструкции, снижая вертикальные перемещения консоли на 30–35% по сравнению с традиционным армоцементом. Также, при уменьшении толщины покрытия до 200 мм, сохраняется достаточная жесткость конструкции, что позволяет уменьшить материалоёмкость. В результате удлинение консольного выноса на 3–4 м возможно без превышения предельных значений прогибов.

Заключение

Заключение. Исследование показало, что использование ТАБ для кровельных конструкций спортивных сооружений позволяет добиться значительных улучшений в жесткости и материалоёмкости, обеспечивая возможность увеличения пролётов или сокращения толщины покрытия без потери эксплуатационных характеристик. Это открывает новые возможности для проектирования лёгких и эффективных конструкций в условиях южных регионов России.

Purpose of research

Purpose of research. The aim of this study is to analyze the structural capabilities and limitations of using textile-reinforced concrete (TRC) in roofing systems for sports facilities, with particular focus on a stadium roof cantilever structure designed for the climatic conditions of Sochi.

Methods

Methods. The study uses a computational model of a cantilever roofing structure made of TRC, with a cantilever length of 22.735 m and a total width of 84.4 m. Numerical methods with finite element modeling in ANSYS are employed. Loads, including snow and wind, are applied based on the regulatory standards for Sochi. Different scenarios of cover thickness and cantilever length variations are analyzed.

Results

Results. The results show that TRC significantly enhances the stiffness of the structure, reducing vertical displacements of the cantilever by 30-35% compared to traditional reinforced cement. Furthermore, reducing the cover thickness to 200 mm maintains sufficient stiffness, leading to material savings. Extending the cantilever by 3-4 meters is feasible without exceeding the allowable deflection limits.

Conclusion

Conclusion. The study demonstrates that the use of TRC in roofing structures for sports facilities leads to significant improvements in stiffness and material efficiency, allowing for either increased spans or reduced cover thickness without compromising performance. This presents new opportunities for the design of lightweight and efficient structures in the southern regions of Russia.
