The use of damping devices to increase the seismic resistance of frame buildings

Abstract

Frame system is one of the most common types of systems in the construction and design of buildings and structures due to their •flexibility• in the choice of design solutions, which, as a result, allows you to use this system in buildings and structures for various purposes, and in different natural and climatic conditions, including in conditions of high seismic activity. However, the analysis of consequences of strong earthquakes showed that many of the frame buildings during seismic effects get serious damage caused by the destruction of their joint connections, and as a consequence, instability of the frame to seismic shocks, therefore, the issues of reliability and safety of operation of buildings are important for their functioning. One of the ways to increase seismic resistance is the use of various means of seismic protection, including earthquake extinguishing devices in the form of dampers, which are widely distributed in the world. However, their application in the domestic practice of earthquake-resistant construction is limited. The article presents an overview of damping devices and conducted a computational study of the effectiveness of traditional and non-traditional solutions in the form of dampers in frame multi-storey buildings to increase their seismic resistance.
