ВЛИЯНИЕ ВЗАИМОДЕЙСТВИЯ ГРУНТ–СООРУЖЕНИЕ НА РЕАКЦИЮ ВЫСОТНОГО ЗДАНИЯ ПРИ ЗЕМЛЕТРЯСЕНИИ EFFECT OF SOIL-STRUCTURE INTERACTION ON STORY ACCELERATION RESPONSE OF A HIGH-RISE BUILDING

Аннотация


Исследуется влияние основания на ускорения конструкций высотного здания при землетрясениях. Для этого выполнены совместные расчёты основания и конструкции 40-этажного здания для шести различных типов грунтовых условий и десяти различных записей землетрясений. Результаты показывают, что учёт в расчёте жесткости основания может привести как к увеличению, так и снижению ускорений конструкций здания, особенно на относительно слабых грунтах. При этом большое значение имеет качество определения характеристик грунта основания. Максимальные ускорения в соответствии с расчётами возникают в центральной (по высоте) части здания, между пятым и пятнадцатым этажами.
