Relevance. Increasing the density of urban population requires the use of optimal structural systems of multi-storey civil buildings, however, despite a large number of studies on the rationality of their application, the question of choosing an assessment of seismic resistance of structural systems of multi-storey civil buildings is still open. The aim of the study. This study aims to determine advantages and disadvantages of structural systems of multi-storey buildings in seismic areas. Methods. The results of comparison analysis of five structural systems (columns grid - 6×6 m, storey height - 3 m, number of storeys - 20) are presented in this article. The structural systems are: frame & tube, frame & core, core & walls, framed core & walls, framed core & tube. The calculation were done according to Building Code 14.13330.2018 for an earthquake of 8 points intensity of MSK-64 intensity scale. The SCAD Office software package was used for modeling and analyzing. The sum of the effective modal masses taken in the calculation was at least 90% of the total mass of the system excited in the direction of the seismic action for horizontal impacts and at least 75% - for vertical impacts. Results. The comparison was carried out according to the following criteria: maximum displacements, maximum compressive and tensile stresses, maximum periods of natural oscillations, maximum accelerations.

Актуальность. Увеличение плотности городского населения требует применения оптимальных конструктивных систем многоэтажных гражданских зданий, однако, несмотря на большое количество исследований о рациональности их применения, вопрос о выборе оценки сейсмостойкости конструктивных систем многоэтажных гражданских зданий остается открытым. Цель исследования - определение преимуществ и недостатков конструктивных систем многоэтажных зданий в сейсмических районах. Методы. В статье представлены результаты сравнительного анализа сейсмостойкости пяти различных конструктивных систем многоэтажных гражданских зданий (сетка колонн - 6×6 м, высота этажа - 3 м, количество этажей - 20): каркасно-стеновой, каркасноствольной, ствольно-стеновой, каркасно-ствольно-диафрагмовой, каркасноствольно-оболочковой. Для реализации поставленной задачи использовался программный комплекс SCAD Office. Расчет был произведен в соответствии с СП 14.13330.2018 для расчетного землетрясения интенсивностью 8 баллов по шкале MSK-64. Сумма эффективных модальных масс, учтенных в расчете, составила не менее 90 % общей массы системы, возбуждаемой по направлению действия сейсмического воздействия для горизонтальных воздействий, и не менее 75 % - для вертикального воздействия. Результаты. Сравнение проводилось по следующим критериям: максимальные перемещения, максимальные сжимающие и растягивающие напряжения, максимальные периоды собственных колебаний, максимальные ускорения.
