ДИНАМИЧЕСКИЙ АНАЛИЗ СОЕДИНЕННЫХ СЕЙСМОИЗОЛИРОВАННЫХ ЗДАНИЙ, ПРИ СЕЙСМИЧЕСКИХ И ВЗРЫВНЫХ ВИБРАЦИЯХ Dynamic analysis of base isolated connected buildings subjected to seismic and blast induced vibrations

Аннотация


Исследуется пассивное управление близко расположенными сейсмоизолированными зданиями при воздействии землетрясений и вибраций, вызванных взрывом. В работе предлагается установка вязких жидкостных демпферов в качестве защиты. Исследуется поведение соединенных сейсмоизолированных зданий при заданных динамических нагрузках. Спроектированные изоляторы из свинцовой резины рассматриваются в рамках модели Bouc Wen. Основание плотное; жесткость грунта, а также отток энергии в него не учитываются. Проводится параметрическое изучение оптимальных демпфирующих свойств для соединенных сейсмоизолированных зданий с вязкими демпферами. Результаты свидетельствуют об эффективности метода пассивного управления с использованием вязких демпферов жидкого типа для уменьшения смещений сейсмоизолированных конструкций, подверженных сейсмическим и взрывным вибрациям.
