Nowadays, various systems of seismic protection are applied to assure seismic protection of buildings and structures, located in earthquake areas. The greatest prevalence and popularity has been attained by the systems of active seismic protection.In this article, the authors study the efficiency of application of an active seismic protection system by taking high-damping rubber elastomeric isolators as an example. Calculations and their comparative analysis were made for a high-rise reinforced concrete building, and their exposure to the seismic impact was examined. Those calculations were made both with and without the application of the active seismic isolation system. Calculations were carried out by means of the linearly-spectral method using Lira software. Maximum relative horizontal moments arising on the top of the building and forces applied to the elements of walls and columns were compared. On the basis of the results of the calculations and their comparative analysis, the conclusion is drawn that elastomeric isolators may be efficiently applied as an active seismic protection system.
Освещены вопросы применения различных систем активной сейсмозащиты, в т.ч. резинометаллические опоры (РМО), для защиты от землетрясений зданий и сооружений, расположенных в сейсмически опасных районах. Рассмотрен линейно-спектральный расчет железобетонного здания с применением системы активной сейсмоизоляции в виде РМО и без нее в программном комплексе «Лира». Произведен сравнительный анализ результатов расчета.
