Wind Effects on the World's Tallest Building

Description

The proposed project aims to investigate wind effects on Taipei 101, the world's tallest building through field monitoring, wind tunnel tests and numerical analysis. This study will be conducted in three closely related phases. The first part involves establishing a comprehensive field measurement program to produce a highly valuable set of field data including wind speed and direction, wind-induced displacement and acceleration responses. In Phase 2, a wind tunnel study of the wind-induced responses of the tall building with proper modelling of the 660-tonne tuned mass damper (TMD) will be conducted. Phase 3 will involve studies on correlating the dynamic characteristics and wind-induced responses from the field measurements and numerical analysis. 3-D finite element models will be built to model the structural system including the TMDs. The numerical model will then be updated based on the field measurements. Finally a computational framework will be developed to predict the structure-TMD responses.
