Wind tunnel model studies to predict the action of wind on the projected 55m Jakarta Tower

摘要

A study of wind effects was carried out at the Boundary Layer wind Tunnel Laboratory (BLWTL) for the projected 558-m high free-standing telecommunication and observation tower for Jakarta, Indonesial. The objective were to assist the designers with various aspects of wind action, including the overall structural loads and responses of the Tower shaft and the antenna superstructure, the local wind pressures on components of the exterior envelope, and winds in pedestrian areas. The designers of the Tower are the East China Architectural Design Institute (ECADI) and PT Menara Jakarta, Indonesia. Unfortunately, the project is halted due to the financial uncertainties in Indonesia. At the time of the stoppage, pile driving had been completed and slip forming of the concrete shaft of the Tower had begun. When completed, the Tower will become the world's tallest free-standing structure, exceeding the height of the CN-Tower in Toronto, Canada by some 5m.
