ЧИСЛЕННАЯ МОДЕЛЬ ФУНКЦИОНИРОВАННИЯ УПРУГО-ПЛАСТИЧЕСКИХ СЕЙСМОИЗОЛЯТОРОВ В МНОГОЭТАЖНЫХ ЗДАНИЯХ

ЧИСЛЕННАЯ МОДЕЛЬ ФУНКЦИОНИРОВАННИЯ УПРУГО-ПЛАСТИЧЕСКИХ СЕЙСМОИЗОЛЯТОРОВ В МНОГОЭТАЖНЫХ ЗДАНИЯХ

Abstract

Introduction of non-linear elastoplastic elements leads to the inevitable coupling of vibrational modes, able to exchange energy. In this case the reduction of the original multiply connected equation system to separate differential equations (producing the solution by the spectral method) is impossible. The author proposes a procedure to calculate buildings equipped with seismoinsulators both kinematic and elastoplastic. This procedure is based on numerical simulation of nonstationary processes of dynamic interaction of nonlinear coupled subsystems.

Введение нелинейных упругопластических элементов приводит к неизбежной связанности колебательных мод, способных осуществлять энергетический обмен, в этом случае приведение исходной многосвязной системы уравнений к раздельным дифференциальным уравнениям (дающим решение спектральным методом) невозможно. Предложенная автором статьи методика расчета зданий, снабженных сейсмоизоляторами как кинематическими, так и упругопластическими, основана на численном моделировании нестационарных процессов динамического взаимодействия нелинейно-связанных подсистем.
