The Application of Dynamic Damper in the Beam Type Structures of Public Building
Abstract: The paper deals with the option vibrations damping of steel girders decorative elements of the main entrance of public buildings that are subjected to the effects of eddy excitation of vibrations in the wind flow. The full-scale dynamic tests of structures have been described, in which their main dynamic characteristics have been identified. The analysis of test results showed the necessity of installing additional devices (dampers) to decrease the vibration amplitude at the resonant mode. The calculation, which takes into account the combined effect of the girder and damper, to determine the optimal parameters of dynamic damper of vibrations has been made. The plate dampers of vibrations have been made and erected on the construction. The full-scale dynamic tests of constructional operation with vibration dampers and without in order to obtain a piece of information of application efficacy of plate dampers have been carried out.
Keywords: dynamic damper of vibrations, dynamic tests, eddy excitation of vibrations.
