DEVELOPMENT OF WIND TUNNEL TEST SYSTEM CONSIDERING PASSIVE CONTROL OF TALL BUILDING AND FUNDAMENTAL STUDY ON WIND RESPONSE : Wind tunnel tests of tall building having viscous or visco-elastic damper under uniform flow

Abstract

In this paper, the wind tunnel test method for a building with either viscous damper or visco-elastic damper is developed. The test set-up includes a special measurement system to obtain the damper hysteresis loop, which is extremely useful to understand the dynamic characteristics of the damper and the system. The damper and system responses obtained from the free vibration tests and the wind tunnel tests using uniform flow are discussed. Three-dimensional heat transfer analysis and static analysis using the same finite element model of the visco-elastic damper are performed in order to estimate the temperature distribution of the visco-elastic damper under the wind loading.
