Abstract

This study is to gain an understanding and develop a test rig for high-rise building isolation for ground motion in vibration and noise phenomenon in Malaysia. In this study a 7-storey high rise building structure with actual scale will be developed. There are three types of simplify structure base such as a pure force, rigid body and short resonant beam. These bases will be connected to the ground structure of building via a single isolator. The outcome of this study is to express the frequency averaging energy transmission or the peak amplitude transmission to the ground structure motion in terms of approximate source and isolator mobility formulae. Theoretical predictions will be compared with experimental measurements. It is useful to predict an energy transmission from ground motion from building, more profound understanding and greater confidence on the approach will not be gained unless measurements can be made. The methods called frequency domain acceleration data and structural frequency response information will be used in this study. These methods are chosen because there is energy input to the structure at a single isolator, and then the energy will be transmitted through an isolator using acceleration at the top and bottom. The energy then will be absorbed by finite resonant structure using accelerations at one, two or four points. By right, after completing this study and experiment, the response on ground isolator of high-rise building can be understood in depth.
