ПОЛЕВЫЕ ЭКСПЕРИМЕНТАЛЬНЫЕ ИССЛЕДОВАНИЯ ДИНАМИЧЕСКОГО ВЗАИМОДЕЙСТВИЯ “ГРУНТ−СООРУЖЕНИЕ” Research on soil-structure dynamic interaction under the field simulated ground motion tests

Аннотация


Проведены полевые испытания 15-этажного железобетонного каркасного здания при вибрационном воздействии на массив грунта. Определены собственные частоты для основания и модальные коэффициенты демпфирования надстройки, которые сравниваются с результатами, полученными при пульсационном воздействии. Результаты испытаний свидетельствуют о повышении точности амплитудно-частотной и фазо-частотной характеристик и уменьшении погрешностей при измерении разности фаз.
