Аннотация


Для зданий с сейсмоизолирующими фундаментами необходимы гистерезисные устройства, чтобы контролировать деформации в изолирующей системе и рассеивать энергию, аккумулируемую под воздействием землетрясения. Uобразные амортизаторы обеспечивают диссипацию энергии за счет пластической деформации специально разработанных стальных элементов. В данной работе исследуются характеристики системы сейсмоизоляции здания, а также приведено сравнение этих амортизаторов с изоляторами из свинцовой резины на примере испытаний 5этажного здания. Нелинейный временной анализ проводился для четырех различных подвижек грунта, вызванных землетрясением. Результаты показали, что для обеих систем изоляции отклик
сооружения значительно снижается, а структурные повреждения минимизируются, но Uобразные стальные амортизаторы более эффективны.
