Abstract

The article considers the use of tuned mass dampers in high-rise construction for significant acceleration and amplitude of vibrations of the upper floors under dynamic wind influences. The susceptibility of people to accelerations in high-rise buildings and possible means of reducing wind-induced fluctuations in buildings are analyzed. The statistics of application of tuned mass dampers in high-rise construction all over the world is presented. The goal of the study is to identify an economically attractive solution that allows the fullest use of the potential of building structures in high-rise construction, abandoning the need to build massive frames leading to over-consumption of materials.

In the present work tuned mass dampers are considered, where the mount plays the role of spring, connecting the bearing structures and the mass and forming a pendulum

Summary

Introduction

The construction of high-rise buildings requires the attraction of advanced achievements in many fields of civil engineering and related sciences. In order to implement ambitious construction projects, that may become symbols of cities and countries, it is necessary to conduct works on the economic substantiation of construction, architectural design, site conditions, the choice of building materials, construction design, development of building technology and its safe and durable operation. The specialists of each of the indicated directions face unusual for their practice challenges when they deal with such projects. In this case, a large number of tests in the design of high-rise buildings fall to the share of engineers who develop building structures, whereas the situation is often aggravated by unfavorable conditions of the construction site, related to possible intense wind and seismic effects
