Three different categories of building from three to five storey are considered for the numerical modelling namely set back building (SB), step back building (SBB) and step back set back building (SBSB). The dynamic response of different buildings are analyzed and compared to assess the seismic vulnerability associated with each buildings. The seismic vulnerability is accessed by comparing the base shear, drift, displacement and torsion factor values. Linear static method is used for the calculation of earthquake load using ETABS. It is observed that SBB and SBSB are highly affected by torsion compared to the SB building. It is desirable to use shear wall in periphery of the bottom storey to improve seismic performance of building. The results in this paper can be employed for construction of buildings with seismically active sloping ground.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Рассматривается поведение конструкции зданий, расположенных на наклонном основании, подверженных сейсмической нагрузке. Для компьютерного моделирования выбраны три категории конструкций малоэтажных зданий, а именно: здание с колоннами разной высоты по всему наклонному основанию (SBSB), здание с обычными по высоте и укороченными колоннами на наклонном основании (SBB) и аналогичное здание на плоском основании с колоннами одинаковой высоты (SB). Динамические отклики этих типов конструкций рассчитывались и сравнивались для оценки сейсмической устойчивости каждого здания. Сейсмическая устойчивость определялась сравнением значений сдвига, дрейфа, смещения и коэффициента кручения у основания. Линейный статический метод использовался для расчета сейсмической нагрузки в программе ETABS. Замечено, что конструкции SBB и SBSB сильно подвержены кручению по сравнению с конструкцией SB. Желательно использовать диафрагму жесткости по периметру нижнего этажа для улучшения сейсмических характеристик здания. Полученные результаты могут быть применены при проектировании зданий на сейсмически активном наклонном основании.</p></trans-abstract><kwd-group xml:lang="en"><kwd>step back building</kwd><kwd>step back set back building</kwd><kwd>set back building</kwd><kwd>seismic load</kwd><kwd>sloping ground</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>здание с уступом</kwd><kwd>SBB</kwd><kwd>SBSB</kwd><kwd>SB</kwd><kwd>сейсмическая нагрузка</kwd><kwd>наклонное основание</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kumar S.
