Fundamental Study on Wind Response Control of Structures Using the Inertial Mass

Abstract

This paper describes fundamental characteristics of wind response control of structures using the inertial mass. The change of mass, damping parameter, natural period, Scruton number are defined using the inertia mass ratio γ. Using a condensation single-degree-offreedom model of a super high rise building, the response is simulated under white noise and external wind force. From the results, reduced effect of the acceleration response is found. The aerodynamic stability of structures by the inertia mass is investigated by means of modified hybrid vibration technique. It is found out that the inertial mass has effect of aerodynamic stability of structures.
