Windtech undertook the wind tunnel study for this 275m high tower in Jakarta, Indonesia. Due to its slenderness and regular plan form, cross-wind loads slightly exceeded the predicted along-wind response and earthquake loads. A decision was made to engage Windtech to design and commission tuned liquid dampers with long-term monitoring to monitor the tuning of the dampers. The aim is to bring about a reduction to the cross-wind response to a level that is equivalent to the along-wind.
