Tasks of laboratories of dynamics buildings and structures

Abstract

EN: The report analyzes a set of problems associated with the dynamics of buildings and structures. Moreover, not only the traditionally problematic tasks of clarification, for example, nonlinear properties of models and types of loads, but also new problems that reveal new possibilities for studying and using the dynamic characteristics of objects. In the 21st century, a new look is needed on the dangers of dynamic impacts and on the protection of objects from them. Every year, even new bright buildings are destroyed by wind, earthquakes, traffic flows and terrorist attacks, which leads to tens and even hundreds of human victims. In addition, urban residents feel discomfort from transport, industrial and construction seismic. Such tasks arise not only for designers and builders, creators and engineers responsible for the operation of structures, soil massifs, environments and machines. But also in front of scientists, developers of new standards and software systems. In this report the author develops and summarizes ideas presented by him in his dissertations on the dynamics of freight cars (1978), buildings and structures (1998), and works, as well as his colleagues in their doctoral and PhD theses on the dynamics of various real structures and objects. These are V. Banakh (dynamics of the urban environment with complex foundations), V. Redchenko (dynamic tests of bridges), I. Davydov (structures with moving loads), V. Chaban (suspended structures, nonlinearities and flexible threads), D. Yaroshenko (development theory of damping devices and patents for dynamic vibration dampers), A. Makarov (dynamic diagnostics of loading cranes up to 150 m long), A. Banakh (strength and vibration comfort, buildings on subsiding soils), A. Maslovsky (nonlinear dry friction dampers) and others.
