The methodology for seismic performance evaluation of a residential building in Indonesia with the use of seismic isolation is considered. An 8-storey reinforced concrete frame residential building with shear wall structural system was selected as a case study. Nonlinear methods of seismic response analysis were used to calculate the response of the structure: nonlinear static (Pushover) and Nonlinear-Time History Analysis, NLTHA. The analysis is performed in STERA 3D freeware. The nonlinear time history analysis was performed for seven pairs of horizontal components of earthquake ground motions, selected according to the parameters of possible earthquakes for the considered site (Bandung city). The selected earthquake records were modified using the spectral matching procedure for design spectrum. Friction-pendulum bearings developed by Nippon Steel Corporation of Japan were used as seismic isolation. The results of nonlinear time history analysis show that shallow earthquakes result in greater damage compared to megathrust earthquakes, with both scenarios providing a life safety (LS) performance level. The use of seismic isolation can reduce seismic loads, as evidenced by the reduction in top-level accelerations and shear forces at the base.

Рассмотрена методика оценки сейсмостойкости жилого здания в Индонезии с применением сейсмоизоляции. В качестве объекта исследования выбрано 8-этажное жилое железобетонное здание рамно-связевой конструктивной схемы. Для анализа отклика сооружения использовались нелинейные методы расчета на сейсмическое воздействие: нелинейный статический (Pushover) и нелинейный динамический анализ во временной области (Nonlinear Time History Analysis , NLTHA). Расчет производится в свободно распространяемой программе STERA 3D . Динамический расчет осуществлялся на семь пар горизонтальных компонент акселерограмм, выбранных в соответствии с параметрами возможных землетрясений для рассматриваемой площадки строительства (г. Бандунг). Выбранные записи землетрясений изменялись с помощью процедуры спектрального соответствия (spectral matching) нормативному спектру ускорений. В качестве сейсмоизолирующих опор были использованы фрикционно-маятниковые опоры, разработанные японской корпорацией Nippon Steel . Результаты нелинейного временного анализа (NLTHA) показывают, что поверхностные землетрясения (shallow) приводят к большим разрушениям по сравнению с мегаземлетрясениями (megathrust), причем в обоих сценариях обеспечивается уровень безопасности жизнедеятельности (Life Safety). Применение сейсмоизоляции позволяет снизить сейсмические нагрузки, о чем свидетельствует уменьшение ускорений на верхнем уровне и сдвигающих усилий в основании здания.
